Bedbugs cause considerable irritation and loss of sleep in afflicted individuals. The presence of bedbugs in hollow bed heads has been blamed for the unpopularity of these items in past years. When investigators arrive at the scene of a crime, they rely on a number of procedures to allow them to determine what has transpired. A technique which is gaining in popularity as it is refined is that of forensic entomology , or the use of insects in crime scene investigations. Each species of fly has different preferences as to the conditions under which it lays its eggs.
Some flies are only active during the day, others at night.
Some prefer to lay their eggs in shaded areas, while others do it in direct sunlight. Some flies will commence laying eggs as soon as the animal stops moving, while others wait until the corpse has started to decay before they lay their eggs. Surely all maggots look the same. Thankfully, maggots do have some distinguishing characteristics, such as the shape of their mouthparts, and the patterns present on their anterior and posterior breathing spiracles. Over longer periods of time, other sorts of insects may be used, such as moths or beetles.
