Some April Insects

by Carl Strang

Insects began to appear during April’s warm spells. Inevitably I have been comparing my finds at St. James Farm Forest Preserve to my experience at Mayslake Forest Preserve, the site of my previous preserve monitoring. Some of the early insects at St. James Farm are shared with Mayslake.

The red admiral overwinters in the pupal stage.

Another early season butterfly is the spring azure.

Other species I never found at Mayslake.

The six-spotted tiger beetle prowls the trails at St. James Farm, as it does on many forest preserves. I was perennially surprised that I never found them at Mayslake.

One impressive insect I encountered at St. James Farm was entirely new to my experience. I first saw it flying, and I thought I was seeing a large bee fly or a fat bee. Then it landed.

It proved to be a beetle. The bumble bee flower beetle’s name reflects its impressive mimicry.

This is a member of the scarab family, and it feeds from flowers, ripe fruits, and sap-exuding tree wounds.
