Bug o’the Week – Painted Skimmer Dragonflies

Painted Skimmers are in the Skimmer family Libellulidae, which contains many of our more common and more colorful dragonflies, and they’re in the genus Libellula – large, sturdy, showy dragonflies, often with dramatically-patterned wings, that are often referred to as the King skimmers.


Bug of the Week – Gray Comma Butterfly – the Other Comma

Howdy, BugFans,

Gray Commas (Polygonia progne) are in the Brush-footed butterfly family Nymphalidae – “brush-footed” because their front pair of legs is small and “brush-like” and tucked in close to their body making them look like four-legged butterflies.


Bug o’the Week – Water Mite Redux

Water mites are common – abundant – denizens of shallow, quiet ponds, and a few species have adapted to life in rivers and streams. They’re everywhere except Antarctica, in tree holes, deep lakes, bogs, hot springs, rivers, swamps, and marshes. The word “ubiquitous” applies.

Bug o’the Week – Bugs without Bios XVIII

Bugs without Bios is dedicated to insects that stay below the radar (our radar, anyway) as they move through the world – they don’t make it into the field guides, and their internet presence is meager.


Bug o’the Week – Black Blow fly

The BugLady has been stewing about this one for a long time. The flies appear on cue, on mild days in March and April (which they can do because they overwinter as adults). She takes their pictures, gets bogged down identifying them, and files them generically under “bluebottle flies.” The reason for her confusion is that there are similar species in several genera of several subfamilies of the Blow fly family:

This year, the BugLady has decided that it’s time to fish or cut bait, so she’s calling them Black blow flies and getting on with her life.


Bug o’the Week – Small Blue Butterflies redux

The BugLady has been enjoying the recent “tropical” temperatures (in the high 40’s) and her thoughts have been turning to butterflies.  Someone asked her recently what butterflies might be aloft as spring approaches.


Bug o’the Week – Olympia Marble Butterfly

The Olympia Marble (Euchloe olympia), aka Olympian Marble and Olympia Marblewing, is in the family Pieridae (the Whites, Sulphurs, and Yellows).  It’s found in a wedge-shaped patch of ground in the middle of North America, plus some disjunct populations in the Appalachians and Texas, and it’s the easternmost of the seven North American Marbles (Wisconsin and Michigan have the greatest numbers of the species).  Within its range, it is local and uncommon.


Bug o’the Week – Western Conifer Seed Bug

Western Conifer Seed Bugs (Leptoglossus occidentalis) (aka Pine seed bugs) are in the True bug order Hemiptera (“half-wing,” a reference to the two different textures of the front wings and in the Leaf-footed bug family Coreidae, a large family of sometimes-dramatic-looking, sap-sucking insects with pretty cute little nymphs. Coreids produce a buzzing sound in flight and an odor when provoked.
