Today, some recent photos of insects from Mayslake Forest Preserve.
Broad-winged bush katydids have been a personal challenge to photograph. They are very good at staying out of sight, and quick to flush when they know they have been seen. This one was on the move, making it easier to spot, and I was able to go slowly enough to get in a couple shutter clicks.
The banded longhorn beetle closely resembles Strangalia luteicornis, which also recently has been visiting Queen Anne’s lace.
Like Strangalia, the adult banded longhorns visit flowers, but this one is more a woodland species rather than woods edges, and its larvae live in decaying trees. Despite the superficial similarity, it is in a different genus.
Another longhorned beetle, Batyle suturalis, like so many adults in its family, feeds on pollen.
The seven-spotted lady beetle was imported from Eurasia for aphid control.
The introduced lady beetles have proven to be problematic, their competitive and possibly predatory activity driving down our native lady beetle species.
The final two insects are Hymenoptera.
I am accustomed to seeing cicada killers, which indeed capture cicadas to feed their young, in sand soil regions. Where these are finding soil soft enough to dig their nursery tunnels at Mayslake is a bit of a mystery.
