Searching for Life

by Carl Strang

This spring I have been pressing a search for coral-winged grasshoppers, and it has been disappointing. This singing insect historically was found in a few locations in my 22-county survey area, almost always in May, but none of those locations proved to have the species. Other places that match the habitat descriptions in the literature likewise have been lacking in coral-wings.

Though depression as a response to this experience has been tempting, an antidote has been thoughts about SETI. Many people, years of time, and much expensive technology have been devoted to the Search for Extra-Terrestrial Intelligence. Furthermore, despite much thought and searching, life of any sort beyond the Earth thus far has been elusive. Balanced against all that, my frustrated search for a species that globally is in no danger seems a trivial matter.

In compensation, I have been getting into some beautiful areas and seeing wondrous sights.

For example, I found hairy puccoons and common blue-eyed grass at Illinois Beach State Park on May 13.

Wood betony also was in peak bloom on the 13th.

From above, wood betony has a delightful pinwheel shape.

Near the edge of the savanna at Illinois Beach State Park, this dung beetle busily rolled a deer fecal pellet.

An Indiana site added Indian paintbrush to the wildflower mix.


The Miller Woods Trail of Indiana Dunes National Lakeshore was flanked by banks of wild lupines on May 16.

Scattered hairy puccoons provided delightful contrast with the lupines.

With such wonderful life all around, it’s hard to be too disappointed by the failure to find a single species.



Return to Illinois Beach

by Carl Strang

A return to Illinois Beach State Park was called for last week, as my first visit was early enough in the season that more singing insects could have become active since. For instance, gray ground crickets were not singing yet in early August, but by last week they were active.

Gray ground crickets are common in the scattered clumps of grasses and other plants behind the Great Lakes beaches.

Hearing is not seeing, however, and despite my best efforts I could not expose a gray ground cricket for a photograph. They were in the larger patches of vegetation and trapped oak leaves, and it was too easy for them to sneak away when I tried lifting leaves and plant stems to look for the hidden singers. That disappointment was relieved somewhat by an amusing dung beetle.

It was having difficulty moving this far-from-spherical chunk.

I had better luck with grasshoppers. Some members of the grasshopper subfamily Oedipodinae are in the park. These qualify as singing insects, as their displays include wing-rattling flights. I found two species. One, a darker form, was in the savanna near the Dead River.

This appears to be a Boll’s grasshopper, a relatively dark individual of the species. The yellow and black hind wings are hidden when folded at rest.

The beach was another grasshopper habitat.

Some grasshoppers prefer this more open vegetation structure.

A common species was pale and well camouflaged.

This one appears to be a seaside grasshopper.

In the night, I followed a tree cricket’s song as it trilled in the gray ground cricket habitat.

The antenna spots don’t show here, but they clearly revealed that this was a four-spotted tree cricket.

Robust coneheads had become common in the campground woods.

This male sings from a patch of big bluestem grass within the savanna.

I found a few more species to add to the site list, but none were particularly uncommon.
