As we progress into the warm season, more and more insects jump, fly or climb into view. Most of the recent photographic subjects at Mayslake Forest Preserve have been moths or butterflies.
Monarch butterflies have received a lot of attention lately. Here a nearly mature caterpillar nibbles at a common milkweed flower.
The beauty of moths is more subtle. This one is called the confused eusarca, a member of the inchworm family.
The prairies and meadows have produced dozens of tiger moths in the genus Haploa. These all seem to belong to two species.
I identify this one as a reversed haploa. A dark line extends from the midpoint of the leading edge of the forewing to the back corner of the wing.
This one appears to be a LeConte’s haploa. Here the dominant line goes out from the tip of the wing.
Each species is represented by an array of confusing variations on these themes.
It hasn’t been just about moths. Here a Batyle suturalis longhorn beetle visits an ox-eye daisy.
The most dramatic recent insect observation was this Laphria robber fly, with its prey, a honeybee. Laphria are bumblebee mimics.
