SNOWY UROLA MOTH & Bird-DROPPING MIMICS
Small Bird-dropping Moth. Attracted with UV light and photographed June 17, 2016. (Note that there is a similar species, the Olive-shaded Bird-dropping Moth, which has more olive green shading on its wings.)
Giant Eucosma moth. This uncommon species is an excellent bird-dropping mimic. I have found a few individuals at my UV lights in July. Their caterpillars eat Cup Plants (Silphium perfoliatum). I planted several Cup Plants in my garden a few years ago and they are spreading like crazy, which could explain what attracted these Giant Eucosma moths to my yard.
Snowy Urola - a beautiful little moth with satin white wings. These moths are abundant from late May through September.
This moth belongs to the Antaeotricha genus. Two species are difficult to distinguish: the Schlaeger's Fruitworm and the Pale Gray Bird-dropping Moth. Schlaeger's Fruitworm Moths tend to be slightly larger, but there is some size overlap. (Unfortunately, all of the individuals that I have measured have been in the overlap range.)
Exposed Bird-dropping moth, photographed August 21, 2018, at Twin Creek MetroPark. This is the only individual of this species I have seen to date.
