Guest Report post Posted January 22, 2006 Went Trout fishing today with Redwings1.We did not even catch one fish, for our effort. But Mike made a scoop in the stream with his net and came up with a few of these guys. Im not sure what they were, but they were about 1/8" long . We thought they might be March Brown. I :dunno: Pics Leaky Quote Share this post Link to post Share on other sites
Redwings1 0 Report post Posted January 22, 2006 I went back and did some checking...the nymph was the wrong shape for a mayfly and was more likely a caddisfly. From what I can remember and what I just checked on it could perhaps be a black caddis larvae. Quote Share this post Link to post Share on other sites
British mike 0 Report post Posted January 22, 2006 Looks like a very small uncased caddis to me.................but I am still learning American Entomoglogy.... :headbang: ......so maybe I am wrong. Mike Quote Share this post Link to post Share on other sites

Taxon 0 Report post Posted January 23, 2006 Leaky Waders- They appear to be larvae of the Riffle Beetle family, Elmidae. Quote Share this post Link to post Share on other sites
Redwings1 0 Report post Posted January 23, 2006 Taxon - I thought that could be the case as well when I pulled out the bug book...but these were nearly 3 time the size of a riffle beetle. Is there another common bug in that family these could be? Quote Share this post Link to post Share on other sites

Is there another common bug in that family these could be? Redwings1- Guess I'm not understanding what you're saying. Leaky Waders indicated they were appoximately 1/8" (3mm) in length. If that is correct, it would certainly be within the expected size range for Riffle Beetle larvae. Please advise. Quote Share this post Link to post Share on other sites
Redwings1 0 Report post Posted January 24, 2006 My apologies, I must have misread when I looked this up...I went back to my pictures from the last stream sample I did in the fall and the riffle beetles we have are exactly 3mm Quote Share this post Link to post Share on other sites
Taxon 0 Report post Posted January 24, 2006 alder fly......bad Idea.......my bad :dunno: Troutbum7- No need to apologize. Alderfly larvae are really quite similar looking. What distinguishes them are the lateral and terminal filiments. Quote Share this post Link to post Share on other sites
Ethan Bright 0 Report post Posted May 28, 2006 It appears these elmids are a species of Optioservus, based on general gestalt, and the loosely associated picture of the adult beetle (from the same site, different time of year?). There are two species in Michigan and Wisconsin - O. fastiditus and O. trivittatus. Quote Share this post Link to post Share on other sites
