Hi there, I found this insect skittering on the surface of a lake. Is this a terrestrial insect that blew onto the water? I cannot find a similar picture. I thought it might be a caddis species. This was in northern ontario on a canadian shield lake.

Thank you, Richard

Hi Richard-

I believe it to be the aquatic moth, Lomographa semiclarata (Bluish Spring Moth).

Roger,

I believe it to be the aquatic moth, Lomographa semiclarata (Bluish Spring Moth).


I think it's likely L. semiclarata as well, but it's not aquatic as far as I can determine. The larvae feed on alders, chokecerries, juneberries, hawthorns, poplars and Prunus sp. I can't determine where it pupates, but there are no references to underwater pupation.

Yes, I should have said non-aquatic. :-)

Hello and thank you! I had a great deal of fun last night after posting using various keys trying to come up with the species. I did not come anywhere close to the right guess! Thanks again Taxon and Millcreek.
