Selected Short Subjects

The BugLady’s #3 child nailed it years ago when she proclaimed her mother an “Essoterrorist”—someone with a fondness for squirreling away obscure facts. Here are some of the Bug Facts that she’s come across while looking for something else.

False Bombardier Beetle Redux (Family Carabidae)

Bombardier Beetles dark-colored, speedy, long-lived, nocturnal carnivores. Many of the more talented members of the family are able to produce noxious chemicals to spray on their enemies. The False Bombardier Beetle spray consists mainly (80%) of concentrated formic acid (which is also deployed by ants), with some acetic acid and wetting agents thrown in.

Dogwood Twig Borer (Family Cerambycidae)

The Dogwood Tree Borer’s name is a study in confusion. Despite its common name, its larvae have catholic tastes and are at home on a variety of woody plants including plum, viburnum, willow, mulberry, elm, laurel, dogwood, fruit trees, and blueberry. It can be found from the Atlantic through Kansas and the Dakotas.

Dining on Dogwood (Family Cerambycidae)

Cerambycids can be remarkably long-lived—some exist as larvae for a decade and as adults for a few additional years. While their elders feed on flowers, fungi, sap, and leaves, the larvae of many species bore into dead and dying trees—they’re great for decomposition, because their tunnels are doorways for water, bacteria, and fungi.

Seasonal Sights and Sounds

Everywhere you look, you see adult insects, young insects, and the kinds of activity that will result in them. Here are some sights from the BugLady’s walks in southeastern Wisconsin.

Horsemint Tortoise Beetle (Family Chrysomelidae)

Horsemint tortoise beetles (Physonota unipunctata) are horsemint specialists. That name is a bit deceiving, because there are several species of horsemints (genus Monarda) . The Horsemint tortoise beetle is tied to a mint that isn’t generally called Wild bergamot (Monarda fistulosa).

Margined Carrion Beetle (Family Silphidae)

Margined Carrion Beetles are found throughout eastern North America into the Great Plains except, says, in the Deep South. They live in grasslands and, rarely, marshes, but research has shown that they have a preference for deciduous forests. Although a few Silphid family members may be found in trees, the Margined Carrion Beetle stays close to the ground.

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.

Lightning Beetle Redux (Family Lamphyridae)

Lightning Bugs float silently (but brilliantly) over the dark fields and wetlands of June and July, inspiring poets and children of all ages. Also called Fireflies, they are neither flies nor true bugs; they are members of the order Coleoptera and are more correctly called Lightning beetles (LBs). And yes, their ethereal light show is all about sex.
