Talk:Caddisfly

message: 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.

replies: text: 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)
