# Talk:Caddisfly

i have some issues with this article, 
altough caddis flies are can be cased or uncased i believe both forms may live in stagnant and flowing water, also i believe some net spinning caddis flies are cased, whilst others are not. 
Before i make relevent revisions to this article, i wanted to make sure i was right and see if any other concerns existed. 
chhers 
this info is based on http://tolweb.org/tree?group=Trichoptera&contgroup=Endopterygota
and

as Fresh wters of New Zealand 2005 by the newzealand Hydrological society.

You are mostly correct.  Philopotamid caddisflies are net spinners and do not make a case of any sort; they live in a loose silk net that collapses and looks like snot on a rock when lifted out of the water.  Hydropsychid caddisflies, also net spinners and make a case-like structure that is usually referred to as a 'retreat'; their nets are frequently framed and stay intact when lifted.  The distinction between cases and retreats is that cases are usually mobile, and retreats are not.  However there are species that make fixed cases that for some reason are not called retreats (let me see if I can make it more complicated:)!!)  Anyway, there are caddisfly species that occur in fairly stagnant water, and also fairly impacted flowing water.  I threw in some stuff on water quality, life cycles, and allergies today; more when time allows; my info is 'off the top of my head' as they say, but I have studied the little beasties extensively am confident in the accuracy  (DMC Feb 11 2006).
The difference between the retreat and the case is that the retreat is a permanently affixed structure from its construction to its end of use, while a case is a portable structure at the begining of its use. The case may be affixed to substrate at some point during its use, but it is still in effect a portable case. Larvae of the family Brachycentridae, for example, will often affix their portable cases to the substrate for feeding, but then can detach them and drift to a new location. In the case of net spinning families like the Philopotamidae that do not build a retreat separate from the net itself, the net, permenently affixed, serves as the retreat as well.

Is there a better way to do the lifecycle link without using the phrase 'biological life cycle'? DMC Feb 12 2006)

I reworded the piece about larval feeding which made it sound like detritus is a form of aquatic invertebrate; furthermore, it's not what net-spinning caddisflies capture in their nets.  Detritus is processed (mostly for the plankton living in it) by shredders and scrapers.
I added alternative emergence behaviors exhibited by a significant minority of species (crawling out on land rather than transitioning into adults in the surface film alone).
Fixed the "artificial flies" link to point to fly lure since there is no artificial flies page.
Added to the adult activity periods that some species are active in the winter.  These include some species of Dolophilodes and Frenesia.
Made a few other small changes I forgot -- mostly grammatical.

I uploaded a photo of a larva tonight. If anyone thinks it's appropriate, please attach it to the article; I don't feel comfortable doing it since it's my photo.

I believe that there are many grammars made in this article and their maybe many incorrect information as well.

I mean, who was "Caddis?" Was it a person? Proscriptus (talk) 17:01, 28 January 2011 (UTC)
Ah! Could it come from "Cadiz beard," as used in Shakespeare? That refers to a particular beard shape, also called a "Cales" beard or "Caddis" beard, which etymologically would make sense.

From Chris Packham on BBC's Springwatch TV show, 8th June 2011: " 'Caddis' is the name for a strip of cloth. People selling cloth in the Middle Ages used to wear strips of it draped over their bodies to advertise the range of fabric that they had: and that's where the 'caddis' name comes from." Does anyone have a source for this?  ~dom Kaos~ (talk) 14:55, 9 June 2011 (UTC)
The OED online gives a number of meanings for "caddis" all relating to fabric:
1. Cotton wool, floss silk, or the like, used in padding: Scottish writers of the 18th c. applied the name to ‘lint’ used in surgery. Obs.
a1400—1769 
2.

a. Worsted yarn, crewel. Obs.

1530—1721
†b. Hence attrib. as a material. Obs.
1550–1600—1675
†c. Short for caddis ribbon: A worsted tape or binding, used for garters, etc. Obs.
1580—1751
†3.

a. A kind of stuff; perh. of worsted (or ? silk).

1536—1552–3

b. A coarse cheap serge.  [Modern French cadis.] Cf. caddow n.2

1578—1887

Regarding common names- in western New York (Buffalo area) caddisflies were invariably called "sand flies" though obviously they are not. I believe this term for caddisflies was also used along the US shore of Lake Erie.  Parenthetically, There seems to be significantly fewer caddisflies in western New York now than in decades past.

" their bodies tend to be tougher than the building."......what building?....if you mean a hypothetical case then what's the basis for the assertion?...citation needed.

### Other things
Fossil caddisflies have been found in rocks dating back to the Triassic;[3] the group survived the Permian–Triassic extinction event about 252 million years ago.  It's not clear what the second part of this sentence adds. Obviously its ancestors did survive that event, but since it's far from clear that the group existed before then you can't really say the group did.

The affinities of the third suborder, Spicipalpia, I think this group needs to be mentioned in the lead, even if they aren't as numerous, because it was a surprise to suddenly realise there were three suborders.
Done. Cwmhiraeth (talk) 13:30, 20 May 2017 (UTC)
The adult stage of a caddisfly may only survive for a few weeks; many species do not feed as adults and die soon after breeding. It's noted later that some adults eat nectar - but this info would be better in ecology than development
Done. Cwmhiraeth (talk) 13:30, 20 May 2017 (UTC)
I'm totally biased but caddis larvae are important for some birds too, like dippers or some high river ducks. (You don't have to action this but I'm just saying).
I'm sure you are right, and amphibians too, but I found it difficult to find a suitable source. Cwmhiraeth (talk) 13:30, 20 May 2017 (UTC)
Development might be better titled Development and morphology
Done. Cwmhiraeth (talk) 13:30, 20 May 2017 (UTC)
sclerotinised linked in development - probably more useful the first time the term turns up in evolution. Also, The heads are heavily sclerotinised  slightly contradicts that first section, which suggests some families arent sclerotinised much
Done. Cwmhiraeth (talk) 17:41, 20 May 2017 (UTC)
Why doesn't the taxonomic list have the three suborders?
Done. Cwmhiraeth (talk) 17:41, 20 May 2017 (UTC)
A few things to address but then it's good to go. Sabine's Sunbird  talk 07:32, 20 May 2017 (UTC)

Thank you for taking on the review. Cwmhiraeth (talk) 13:30, 20 May 2017 (UTC)
I will leave @Chiswick Chap: to deal with the image issues. Cwmhiraeth (talk) 17:41, 20 May 2017 (UTC)
Done, I believe. Chiswick Chap (talk) 07:37, 22 May 2017 (UTC)
And pass. Good stuff. Sabine's Sunbird  talk 08:08, 22 May 2017 (UTC)
Thank you for the review. Cwmhiraeth (talk) 08:24, 22 May 2017 (UTC)
And from me. Chiswick Chap (talk) 10:04, 22 May 2017 (UTC)

Without being mean to the artist, the mention of Hubert Duprat at the start is superfluous, since he is mentioned later in the correct place. In fact, he is mentioned no less than 4 times in the article, whereas for example, the eminent Jean-Henri Fabre, from whom he draws no doubt, is not mentioned at all, despite his celebrated writing on the caddisfly. That seems... an imbalance, imho. Rsaum (talk) 16:07, 15 August 2024 (UTC)
