Horned Spanworm, Besma moths, Greater & Lesser Grapevine Looper, and Curve-lined Looper
Another Horned Spanworm moth. Some individuals have much darker shading than others.
Curve-lined Looper moth. This individual was photographed at Hocking Hills, but these moths are very common at my home lights as well. I find them in April and May.
This moth might be a Straw Besma, but these are tough to identify. Straw Besmas can look very similar to the paler, lightly-marked form of the Oak Besma.
This is a Greater Grapevine Looper. This species is very similar to the Lesser Grapevine Looper (below), but it is slightly larger. Some sources say that these two species cannot be told apart in photos. However, in a Greater Grapevine Looper, the bottom points on the PM line typically do not reach all the way to the lower edge of the wings. Also, note the grayish shading along the bottom edge of the wings.
Horned Spanworm. These moths visit my lights in June, July, and early August.
Another Oak Besma, photographed at Hocking Hills. These moths are highly variable and some individuals have darker patterns than others.
Oak Besma moth, photographed at Spring Lakes Park in Bellbrook. I have found several individuals in May and July.
Another Lesser Grapevine Looper. This is a faded individual, but the point on the left reaches to the bottom edge of the wings.
For contrast, here is a Lesser Grapevine Looper. The points reach to the bottom edge of the wings. Both of these species rest with their abdomens curved upward.
