Thyreodon atricolor (no common name), one of the BugLady’s “Nemesis Bugs,” is a big, beautiful wasp that flies tantalizingly through dappled, woody edges, preceded by those fabulous, yellow antennae. It seldom stops, and when it does, it often perches in the shade.

The BugLady was walking along the trail at Forest Beach Migratory Preserve recently when she saw a flashy, orange, inch-long wasp actively hunting for something in some white ash saplings. The wasp was flying from tree to tree, searching among the leaves. This week, we’re taking a look at the Trogus Pennator.

The BugLady is spending as much time as she can in the field (and the rest of it editing pictures) because, you know, the Summer Solstice has passed, and a little wave of warblers moved through her yard the other day, and winter is coming. Many of these beauties have already starred in their own BOTW. In a nutshell – there’s a whole lot of romance in the air.

The BugLady is feeling a little cranky. It’s snowing as she’s writing this – 3” to 5” are expected, and the temperatures predicted for the next week mean that the snow’s not going anywhere soon, so the newly-returned robins, cranes and killdeer will be very unhappy – and she’s leading her first woodcock and frog walk in three weeks. To take our minds off of the snow, here are a few insects about which the information is sparse, though they are undoubtedly worthy.

\Someday, the BugLady will write a book about trying to pry information about this wasp from the ether (once she figured out that it isn’t a Sphex or a Podalonia); it will be subtitled (with apologies to Judith Viorst) “Google has a Terrible, Horrible, No Good, Very Bad Day” (and possibly sub-sub-titled “Net Neutrality and Entomological Research? Really??”). Anyway – different pulpit.

This week, The BugLady introduces some insects that, while not totally unsung, still have a pretty low profile.

As the leaves color and fall, some interesting galls are being revealed. Quick review – a gall is an abnormal and localized tissue growth on a plant. Plant galls can be caused by friction, fungi, bacteria, and even by viruses, but for BOTW purposes, we’ll stick to galls that are initiated by animals like insects and mites.

Lately, The BugLady’s been thinking about prairies. She led a walk at Riveredge Nature Center’s excellent “Knee Deep in Prairies” celebration, and she spends a lot of quality time on the prairie because she loves its ever-changing palettes and patterns. By some estimates, the biomass of the insects on pre-settlement American prairies equaled that of the bison. Here are some pollinators and predators and plant feeders of the prairie – and the flowers they visit.

A solitary Four-toothed Mason Wasp, Monobia quadridens, has taken to creating egg chambers in the BugLady’s wind chimes. This is a medium-sized wasp, with both a length and a wingspan of just under an inch. They are found throughout eastern North America, edging into southern Ontario to the north, the Great Plains on the west, and northern Mexico to the south.

Here’s the general formula for gall formation: Mom lays/injects her egg(s) onto/into plant tissue, and when the eggs hatch, the young insects (there are gall-making wasps, flies, beetles, moths, thrips, and aphids) or mites burrows inside, if it’s not there already. Specific gall-makers target specific host plants, resulting in galls that are predictable in location and appearance.
