Hey everybody I just did a color illustration of Epeorus longimanus
based on a sample from the biodiversity group collection @ the university of Guelph. This one bares a big resemblance to that sample.
This one seems more transperent but it is a living sample, and the ones on the site are in preservative.
The median posterial terga bands and the head capsule shape is what made me think this maybe E. longimanus
Just wondering if this is E. longimanus
and if so can it be label it as such ???
Here is the sample I worked off of.
