Species Arge ochropa - Rose sawfly

First described in 1790 by Johann Friedrich Gmelin as Tenthredo ochropus

ochropus is perhaps from Greek ochros (ωχρος)- "pale, pale yellow" + Greek pous(πους)- "foot". If so, the correct spelling is probably ochropus, since it would be a noun in apposition (which doesn't change gender to match the name of the genus) rather than an adjective (which does)

Larva:

An introduction from Europe, it was first reported in Ontario, and more recently recorded from the U.S. and from other provinces in Canada. Mostly in the northeastern part of our area, but can be expected to increase its range.

The larvae feed on the leaves of roses
