A Prelude of Spring Time Hatches!

This video reminded me of all the good things that come with Spring; like trout streams loaded with aquatic insects that have been relatively dormant all winter and are getting ready to do their thing.

Excerpt from video description on YouTube

The water temperature was at 34f and I did most of my collecting from a lip on the head of a pool in about 10-15 inches of water. The bottom substrate was a mix of silt, small gravel, dinner plate size flat rocks and some aquatic vegetation. I found the highest concentration of insects in the fine silt and gravel buried under the larger rocks, nearest the aquatic vegetation.

Some of the insects feature include:

Stoneflies - Capnia and Acroneuria genus
Mayflies - Stenacron, Caenis, Ephemerella and Isonychia genus
Caddis Larva - Hydropsychide and Limnephilidae family
Crane Fly Larva

These aquatic insect larvae were collected in Western New York from a spring fed headwaters that eventually flows into one of Lake Erie's largest tributaries.

If you have been hunkered down all winter, it is time to get off your duff and get out there!

Could Caddisfly Silk Be Used to Make Waterproof Band-Aids?

Now, University of Utah researchers have discovered why the fly’s silk is sticky when wet and how that may make it valuable as an adhesive tape during surgery.” And here I thought caddis were just great [...]

Last Friday night we kicked off our Baetis fly tying video series in anticipation of one of the most prolific mayfly hatches of the season, the Blue Winged Olives. Before we continue the series I thought it might be a good idea to do a quick review of the Mayfly Life Cycle. Fortunately for us, [...]
