Dogbane Leaf Beetle Revisited (Family Chrysomelidae)

Predictably, the Dogbane Leaf Beetle lives and feeds on dogbane (a close relative of milkweed) and on milkweed, too, in edges, open woods, waste spaces, prairies and grasslands over the eastern two-thirds of North America.

Multicolored Asian Ladybug (Family Coccinellidae)

Multicolored Asian Ladybugs (Harmonia axyridis) need no introduction—they’ve been around for a century (especially for the last 30 years). Introduced over the years, they became common in the Midwest about 15 years ago, in the Northeast 20 years ago, and in the Northwest 25 years ago, and its numbers have grown considerably beyond abundant.

Shoreline Rove Beetle (Family Staphylinidae)

Rove Beetles make their living hunting springtails, mites, aphids, and other tiny invertebrates along the marsh and stream edges they inhabit. Whether Stenus is eating the plant tissue or going after another invertebrate feeding there.

Emerald Ash Borer Redux (Family Buprestidae)

Originally from Asia, the Emerald Ash Borer beetle was first discovered in the Detroit, MI area in 2002, but it had probably hitched a ride into this country as much as a decade earlier. Its strong flight typically allows it to increase its range by a mile or two per year, but it doesn’t have to depend on its wings to travel, since humans have been doing the heavy lifting for it.

Where the Lizard and the Antelope (Beetles) Play

The Antelope Beetle is mainly found east of the Great Plains, and it’s one of five Lucanids in Wisconsin, all of which like wooded areas. Lizard Beetles are one of only two members in their genus in North America. Lizard beetles used to have their very own family (Languridae),

Midsummer Report

The BugLady would like to dedicate this episode to the late (great) Cornell Professor Richard B. Fischer (January 19, 1919 – August 7, 2005) who taught the BugLady how to sneak up on insects (no bobbing or weaving, just slow and steady and straight ahead.

It’s a Beetle! Really! (Family Ripiphoridae)

There are about 50 species of these Ripiphorid beetles in North America, and 30 of them are in the genus Ripiphorus. While the general outline of how the family operates has been charted, only one species in the genus Ripiphorus has been studied, and it’s assumed that the other 29 follow the same general pattern.

Rorschach Beetles (Family Chrysomelidae)

Chrysomelid beetles are vegetarians for their whole lives, eating a variety of plant tissues above and below the ground. Their numbers include some serious plant pests like the Colorado potato beetle and the asparagus beetle, and also some species that are used as biological controls. It’s a huge group, with almost 2,000 species in North America alone. Chrysomelids generally produce a single generation per year; most overwinter as adults and hit the ground running in spring.

Bugs Without Bios VIII

Today we feature three bugs about whom not too much information is circulating, other than their presence in museum collections and on state/regional biodiversity lists. If they have anything in common, it’s that all three are odd little insects.

Eyed Elater Click Beetles (Family Elateridae)

Click Beetles (family Elateridae), a.k.a snapping beetles or skipjacks. About a tenth of the world’s 9,300 species live in North America, occupying most habitats except very cold and very wet ones, and deserts.
