Mayslake Update

by Carl Strang

Today I want to share some miscellaneous notes on what has been happening at Mayslake Forest Preserve. Most of these are reflective of the season. For instance, thousands of migrating dragonflies have been passing through in recent weeks. Most of these have been green darners, with some black saddlebags and wandering gliders. I also saw the preserve’s first swamp darners (but was frustrated in my attempt to photograph them as they patrolled the stream). Some of the green darners paused to mate and lay eggs.

Birds also have been migrating. A good mix of warblers and others, including this scarlet tanager, have been refueling on Mayslake’s insects and berries.

Some insects appear late in the season. An example is this adult locust borer, the preserve’s first record of the species.

Of course, our year-round residents continued their activities, with signs of preparation for winter. For example, I have been seeing more skunk tracks than usual, in one case accompanied by scats.

The season’s progress makes this a time of daily change, and time spent outdoors inevitably brings its rewards.
