“The horses in the pasture fidgeted with anticipation when
they heard Mr. Johnson’s lawn mower nearby. Little didanyone know that soon one of them would end up dead as aresult.”By Lisa Carloye, Washington State University
Stephen Bambara, NC State University(Adapted by S. Bambara from “Of Maggots and Murder” by L. Carloye)

This is a hands-on lesson in which 4-H’ers evaluate evidence from four animal deathscenarios. For each scenario, they are given a sample of simulated maggots thatwere collected from a fictional corpse and are asked to figure out the postmortem
interval in which the insects developed and determine whether foul play was
involved in the death. This exercise is adapted from a lesson used by college biology
teachers.

Life Skills:
Critical thinking, problem solving, teamwork, communicating, learning to learn.
Purposes:
1. To appreciate the practical application of entomology in society.
2. To learn the concept of “succession” of insect life in the role of decomposition.
Time:
Four lessons requiring approximately 20 minutes each.
Also included at the end is an optional, related activity involving monitoring insect
succession in a decaying chicken gizzard over several weeks. Review the activity to see if
it can be useful or applicable to your program.

Materials You’ll Need:• Life history of flies sheet (provided, Table 1, page 13, one for each team)• Ecological information sheet (Table 2, page14, one for each team)• Police report information sheets for Cases 1-4 (provided, one set for each team,pages 9-12)• Rulers measuring millimeters (one for each team)• Colored pipe cleaners—white, blue, yellow, pink, and brown• Plastic sandwich bags filled with appropriately measured lengths of colored pipecleaners (1 for each case, 4 for each team)• Scissors (one) to cut pipe cleaners• Forceps or tweezers for each team (optional)• Plastic or latex gloves (optional)
Before the Meeting:
Prepare a Crime Report Pack for each team of 4-H’ers.
The Crime Report Pack contains:• Maggot bag of cut pipe cleaners (4, one for each case using Table 3, page15).
(Label each bag with a case number.)• Police report information sheets (one for each case)• Life history sheet (Table 1, page13)• Ecological information sheet (Table 2, page14)• Ruler measuring millimeters• Four Common Flies Used in Forensic Investigation (photos, provided, one foreach team of 2 or 3 4-H’ers, page 8) (optional)• Forceps and gloves (optional)
Background:
The ordered development of flies on a dead animal is predictable. Because of that, theflies can be used to help determine the time of death or other factors that may have legal
implications. This interactive learning activity was originally developed for use in acollege general biology class to illustrate principles of community ecology and ecologicalsuccession, the idea of an ecological niche, and the role of life history, and to illustrate
how basic biology can have an unexpected practical use.
This activity is of minimal cost and may be conducted without the need of a strong
biological background, either in a classroom or at tables. Each of the four death scenarios
features a slightly different twist and takes about 20 minutes to complete. Each case canstand alone, or all can be worked through sequentially, as time permits.

Lead In:
When an animal dies, flies are among
the first to find and colonize the carcass,usually arriving within 10 minutes ofdeath. As the carcass decays, theenvironmental conditions within itchange. It becomes drier, thetemperature rises, and tissues break
down. In fact, the process of decay is
one of ecological succession whereby aseries of predictable changes occur, in
succession, as the carcass progresses
from the “fresh” stage, where the body is
intact and decay has barely begun, to the“skeletal” stage, when all that is left isindigestible hair and bone. This process
is an example of what is known assecondary succession, whereby an
ecological community begins with thedeath of an animal and its body
represents an isolated, rich source ofresources that is colonized by particulargroups of insects as the body undergoeschanges. The process of colonization andutilization of the body continues until
decomposition is complete.
The progression of insect life follows apattern, and the developmental rates offlies are relatively predictable.
Therefore, if enough information is
known regarding the temperature of the
microclimate in which insects occur, theinsect community associated with acorpse may be investigated by forensic
scientists to estimate the postmortem
interval—the time between death anddiscovery of the corpse. When this typeof information is used in our legal
system, it falls into the category called
forensic entomology.

reading the following paragraphs aloud,one at a time, in order, to the rest of thegroup.]

The four development stages throughwhich flies and many other insects passis called complete metamorphosis.
Here, the insect hatches from an egg intoa white grub, called a larva or a maggot,
which crawls like a caterpillar andactively consumes food to grow quickly.
The insect will pass through several
instars or stages during this process.
Every time it completes a stage, it mustshed a tough or hard exoskeleton andthus molt. Upon reaching larval
maturity, the maggot will darken andturn into an immobile pupa. The pupa
may look inactive, but many changes are
occurring inside the casing. Soon, awinged adult fly emerges. The adults
will then mate, and the females will lay
more eggs onto corpses. The adultfemales often search out the natural body
openings for this. This means that eggs
and larvae begin feeding in the headregion first (mouth, nostrils, eyes, ears),followed by the excretory andreproductive openings. The trunk of the
body is invaded much later in theprocess.
The rate of insect development is
influenced by temperature because
insects are ectothermic (“coldblooded”). That means their bodytemperatures are largely dictated by theoutside temperature. Only when theoutside temperature warms an insect’s
internal body temperature to its criticallevel can the insect become active (andeat and grow).

make estimating the time of death
difficult. Sometimes investigators may
find large maggots on relatively young
corpses and small maggots on relatively
old corpses, which is the opposite ofwhat would usually be expected.
These stages of insect growth, as well as
the order in which certain insect species
invade the corpse, are predictable. For
this reason, the insects can be used toestimate time of death and, in somecases, cause of death. The process of
decay of the corpse begins at the
moment of death. This is the freshstage, and it lasts until the body becomesbloated. At this fresh stage, the body
looks relatively normal—much as if itwere sleeping. Blow flies and flesh flies
are among the first to find the body, andthey can arrive within 10 minutes ofdeath. They lay their eggs, from which
the maggots hatch quickly and begin to
feed on the tissues. (Flesh flies do notlay eggs, but deposit newly hatchedmaggots directly onto the corpse.) Not
all fly species are found everywhere, andthis can provide important information
also. For example, the skipper fly,
Piophila nigriceps (pie-oh-FEEL-ah
NYE-greh-cehps), is found only in urban
settings. Predatory wasps, beetles, orboth may arrive later to feed on themaggots (but not the corpse).

Any drugs present in the corpse at thetime of death can affect the rate ofmaggot development, as they ingest the
drug along with the tissue. A drug likecocaine speeds up development, whilesome poisons, such as arsenic andglycosides, slow it down. This fact can

The bloated stage begins when the body
becomes visibly inflated due to the
production of gases from bacteria thatbegin to putrefy the body or cause it todecompose. House flies now join theother flies, and their maggots form
feeding masses that help to liquefy thetissues of the body. At this point many
maggots feed on the body andcompetition increases, as do the number
and variety of predators that come tofeed on the maggots.
The decay stage begins when the skinbreaks and the gases escape, giving thecorpse a deflated look. The maggot
masses are large and very active as they
continue in their development, growing
older and larger. This is the stage ofdecomposition that smells bad. By theend of this stage, most of the maggots
have finished development (typicallythey molt three times before pupating),
and they begin to leave the corpse in
search of a place to pupate in the soil.
Most of the flesh is gone from thecorpse, with only cartilage, bone, andskin remaining. At this point the
postdecay stage begins. This stage isdevoid of flies, although some beetles
continue to feed on the highly desiccatedor dried remains.

Procedure:
Divide the group into teams of two or three. Hand out a Crime Report Pack to each group. Have themstart with Investigation #1. They will measure the maggot and pupal evidence (the cut-up, colored pipecleaners) to determine the life stages and species found at the scene. Using the life history chart andecological information (Tables 1 and 2), they can work on the answers to the questions of each
investigation. Each investigation can be done separately or in progression, as time allows. Consult youranswer key to work through the questions with the 4-H teams when the assignments are completed.
At the end of the activity, lead the group through the “Let’s Talk About It” questions.

INVESTIGATION #2
Police Report: The body of a large pit bull terrier was found inside a walk-in
basement at a home in Cary. Maggots were found concentrated in the head andregion behind the shoulder. The windows were closed, although the open curtains
allowed sunlight to enter, and the air conditioner was set at 72º F.
Weather Report: Daytime temperatures have been variable over the past three
weeks, ranging from 75 to 94º F. Skies have been sunny.

Questions:
1. Approximately how long has this animal been dead?

2. What effect, if any, do the outside temperatures have on your estimation of time of death?

3. How does the fact that the windows were closed relate to the populations of flies you observed inand around the corpse? (Is there something different about this population than the population in
Investigation #1?) How do you explain the absence of the blow fly, Calliphora vomitoria?

4. Do you suspect foul play? Explain.

INVESTIGATION #3
Police Report: The body of a young male horse was found in a pasture in a small
town near Wilmington. The autopsy from the vet school reveals that the cardiac
glycoside, oleandrin (similar to digitalis, a powerful heart stimulant), was present in
the body. Oleandrin is found in the oleander plant. Oleander is a common ornamental
shrub in this area, but none grows within 200 feet of the pasture.
Weather Report: Daytime temperatures have been unusually warm over the past
three weeks, ranging from 84 to 86º F.
Questions:
1. Approximately how long has this animal been dead?

2. What effect, if any, does oleandrin have on your estimation of time of death? Explain how you
used this information in calculating the postmortem interval.

3. What effect, if any, does temperature have on your estimation of time of death? Explain how you
used this information in determining the postmortem interval.

4. Does the location of the body, coupled with the insects recovered from it, suggest foul play, or can
you tell from the information given? Explain.

Answer Key
INVESTIGATION #1
Police Report: The body of a female deer was
found beside a fence on the edge of the Charlottecity limits. Animal Control was called andreported no apparent wounds on the body. It was
not hunting season.
Weather Report: Daytime temperatures havebeen fairly consistent for the past three weeks,ranging from 70 to 74º F.
Questions:
1. Approximately how long has this animal been
dead? 11 days
2. Why are maggots of different ages found in
the body? Adults of the same species will
arrive at the body at different times. Adults
of different species may also arrive at
different times or they may colonize thecorpse in different stages of succession.
3. Other than temperature, what abiotic (external
to the body) conditions would you want toobtain from the weather station to help you to
be more confident of your time of death
estimation? Humidity, rain, cloud cover (forestimating microclimate differences), andwind.
Remarks: The first case is straightforward.
This helps 4-H’ers become used to theprocedure and to interacting with eachother. One might conclude that the deer
was hit by a car and not illegally shot.
INVESTIGATION #2
Police Report: The body of a large pit bull
terrier was found inside a walk-in basement at a

Crime Solving Insects

home in Cary. Maggots were found concentrated
in the head and region behind the shoulder. The
windows were closed, although the open curtains
allowed sunlight to enter, and the air conditioner
was set at 72º F.
Weather Report: Daytime temperatures havebeen variable over the past three weeks, ranging
from 75 to 94º F. Skies have been sunny.
Questions:
1. Approximately how long has this animal
been dead? 5 days
2. What effect, if any, do the outside
temperatures have on your estimation oftime of death? The outside temperature
has no effect on larval development.
That’s because the windows were closed
and the inside temperature was 72
degrees.
3. How does the fact that the windows wereclosed relate to the populations of flies
you observed in and around the corpse?
(I.e., is there something different about
this population than the population in
Investigation #1?) How do you explain
the absence of the blow fly, Calliphora
vomitoria? Because the windows wereclosed, the only flies that could have laid
eggs on the body were those that werealready present at the time of death.
Thus, C. vomitoria must not have beenpresent, even though we would expect tosee it as an early colonizer.
4. Do you suspect foul play? Explain. YES.
The pattern of colonization indicates thatan orifice was present behind theshoulder (more maggots there than would
be expected). A puncture wound or bullet
hole would be consistent with theevidence.
INVESTIGATION #3
Police Report: The body of a young male horse
was found in a pasture in a small town near
Wilmington. The autopsy from the vet school
reveals that the cardiac glycoside, oleandrin
16

(similar to digitalis, a powerful heart stimulant),
was present in the body. Oleander is a common
ornamental shrub in the area, but none grows
within 200 feet of the pasture.
Weather Report: Daytime temperatures havebeen unusually warm over the past three weeks,ranging from 84 to 86º F.
Questions:
1. Approximately how long has this animal been
dead? 7 days (4-H’ers must account for bothtemperature and drugs when calculating this).
2. What effect, if any, does oleandrin have on
your estimation of time of death?
Explain how you used this information in
calculating the postmortem interval.
Oleandrin speeds up development of
Calliphora vomitoria (blow fly) by 2 to 3days.
3. What effect, if any, does temperature have on
your estimation of time of death? Explain
how you used this information in
determining the postmortem interval.
Temperature speeds up development, thus wemust subtract the number of days that
accumulated due to temperature rather thanthe passage of time.
4. Does the location of the body, coupled with
the insects recovered from it, suggest foulplay, or can you tell from the information
given? Explain. No. The fact that Prophila
nigriceps (skipper) was not found on the
body is consistent with the location in which
the body was found. However, the presenceof oleandrin raised suspicions. It was later
determined that a neighbor, Mr. Johnson,
usually fed the horses his lawn clippings. The
horses knew of the upcoming treat by thesound of the mower. Unfortunately, someclippings from Mr. Johnson’s recently
pruned oleander bush were left on the groundin his yard and became mixed with the grassclippings.

INVESTIGATION #4
Police Report: The body of a large potbellied pig was found in a dense stand of
evergreen trees far from any urban areain Buncombe County. Hairs around the
pig’s neck were worn away in a band
pattern.
Weather Report: Daytime temperatures
have been average over the past three
weeks, ranging from 70 to 73º F.
Temperatures in the woods would beapproximately 5 degrees cooler due to thelack of sun in the shady environment.
Questions:
1. Approximately how long has this animal
been dead? 10 days
2. What effect, if any, does temperature haveon your estimation of time of death?
Because it is cooler in the forest, maggot
development is slowed; thus you must
add days to the number of days it appears
the maggots have been developing.
Cooler temperature slows the growthabout 2 to 3 days, depending on thespecies.
3. Does the location of the body, coupledwith the insects recovered from it,suggest foul play, or can you tell from theinformation given? Explain. Because the
Piophila nigriceps skipper occurs only inurban habitats, its presence indicates thepig died in an urban habitat and was
moved to the woods at least five days
after death. The missing-hair pattern on
the neck suggests a pet’s collar.

Let’s Talk About It:
Sharing: How do you feel about this topic? What was the hardest aspect of this activity?
Do other insects appear on corpses? Which kind? [Example: Silphid beetles prey on themaggots.] Is it “good” or “bad” that insects eat an animal corpse? What are some of thechallenges of working with team members?
Processing: What different species of flies did we use to determine the ages of thecorpses? What does the order of insect arrival mean to a forensic entomologist? Whatmight you find if an animal had been left dead for six months? What other types of data
might police look for at the scene or in a laboratory? [Example: Footprints, tire tracks,chemicals in blood, DNA.] Why is it important to know about insects?
Generalizing: What other situations like this have you experienced in which you makeobservations and try to solve a puzzle? When have you used data to prove a point? Why
is it important to collect all the information about the case before making a judgment?
[Early conclusions may be different or wrong.] What are some other examples ofsuccession that involve species other than insects? [Plant species vary in different aged
fields and forests.]
Applying:
Can you think of any other situations where entomology expertise could be used in legal
matters? [Example: If someone was sold infested products, such as grain (flour) or evenbaked goods, determining if the infestation came during or after production might help
assign liability.] Would this type of information apply to humans? Assigning liability inthe cause of a dead tree? What if you found insects on recently purchased shrubs? Whatif you have termites in the house you purchased 6 months ago?
How can you apply this thinking process to evaluation of issues at home or school? Whatwould you do differently if you conducted this activity again? When have you had tomake an educated guess, and how did it turn out?

Optional Activity
For this activity, 4-H’ers may work in teams or separately with parents. Results may bereported and compared at subsequent meetings. Alternatively, this could be conducted as
part-activity and part-demonstration. This might be useful at a “camp” setting where
ahead of time the leader exposes fresh chicken gizzards or livers to the outdoors at oneweek intervals and labels them so that the succession process can be observed on thespot.
1. Obtain a chicken gizzard or liver from the leader. Place the gizzard in an open
plastic container and use a permanent marker to identify your container.
2. Place the container outdoors for about 30 minutes. Flies will find the “corpse” andlay eggs on it. Reasonably nice weather and temperature are important.
3. Return the container indoors. Cover it with a lid that allows a little ventilation, but
not access by other insects. Check your corpse for the next three weeks or until
the next meeting. Using the Data Sheet at the end of this unit, take note of what
you see and when, and indicate the organisms you find and the condition of thecorpse.
