Summer Survey

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.

Bugs without Bios XII

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.

Palmodes dimidiatus (wasp)

\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.

Bugs Without Bios XI

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

Galls V

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.

Way Out on the Lonesome Prairie

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.

Four-toothed Mason Wasp (Family Vespidae)

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.

Galls IV – Two Oaks and a Hickory

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.

Ichneumon centrator Wasp (Family Ichneumonidae)

Ichneumon centrator (no common name) is about ¾” long. Females are black with smoky wings, reddish-brown accents on the thorax and head, mostly-pale antennae, and dark yellow bands on their legs. Males are black, with pale antennae. Only one host species has been identified for Ichneumon centrator, and it’s the larva of the Isabella tiger moth, famously known as the Wooly bear caterpillar.

Wildflower Watch – Dawdling among Dandelions

Dandelions produce both nectar and pollen and so are appreciated by wildlife, especially early bees and butterflies (100 species of pollinators have been tallied). The BugLady has been dawdling among dandelions to see who else appreciates them. She saw representatives of 8 kinds of hymenopterans (ants/bees/wasps), 4 kinds of flies, 3 of arachnids (spiders and spider relatives), and 1 beetle. Seen, but not photographed, were a few cabbage butterflies.
