Winter Critters
December 30, 2009
I took a walk in the woods this month in western New York and found many little critters on top of the snow. I would appreciate any help you might be able to give in identifying. The trails are on a 600-acre wetland preserve and most of the pictures were taken in mixed woods of pine, hemlock, cherry, maple, oak, etc. that surround a very slow-moving marshy pond.
All of the pictures can be found on my blog (which links to bigger versions on Flickr): http://winterwoman.net/2009/12/23/snow-critters/
There were some spiders, too… Can you help with them?
Thanks in advance for your help!

Caddisfly

Caddisfly

Hi again Jennifer,
Your third image is of a Caddisfly, but we don’t want to try to identify it any further than the order Trichoptera, or possibly the Northern Caddisfly family Limnephilidae.  We did find a reference on a fishing website to Winter Caddisflies in the genus Psychoglypha that are called Snow Sedges.
Troutnut.com also has this comment posted:  “Dr. George Roemhild explained to me how he finds these winter caddisflies in February and March: ‘They crawl up on the snowbanks, but when the sun hits their dark wings they melt down out of sight. That’s how I collect them, by walking along looking for holes in the snow.'” We also found a reference to Snow Sedge on the Flyfishing Entomology website, our new favorite etymology reference page.  Your second image, the caterpillar, is some species of Cutworm.

Wow.  You’re my hero.  thanks a billion.  Now I’m going to have to write a blog post about the wonderful folks over at What’s that Bug!!!

Here’s my blog post:
