Can you provide a size for this specimen? 2 Replies »
Jason-
I hate to ask you to dig through your specimen vials, but I'm curious to know if you can give a size reference for this one. I've stared at it many times. My first impression was Brachycentrus, but that impression was based entirely on color and markings. I haven't been able to find any definitive keys to verify this id (though I may be missing something).
May 18 does seem a little on the late side for most of the common Eastern/Midwestern Brachycentrus spp. But, we do have a peak emergence of a Micrasema sp. around that time on the Brodheads. This is the reason I was wondering about the size. I also wanted to call attention to this specimen in the hope that Litobrancha, Taxon, or someone else might be able to end my puzzlement. (I'm also curious about that bright spot on the scutellum. I can't recall noticing that on other Brachycentrids--if that's what this is.)
