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.

Befroe 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).

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

[edit] Made some small improvements today

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.

[edit] A new photo of a case carrying larva

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.
