Found at a light, posed. Body length, head (not including antennae) to tip of abdomen, 15 mm. Length to tip of folded wings about 19 mm.
Looks similar to this individual, found at the same site about one year earlier:
We don't have too many of these in the guide, and perhaps some day we'll be able to assign these to species. (Assignment of New World species to genus Mantispa
may have been changed, I understand, as well.) See comments.
