Minute Pirate Bug - Dufouriellus ater

Minute Pirate Bug - Dufouriellus ater
Richmond Hill, York Region, Ontario, Canada
June 12, 2007
Size: 2 mm
As can be drawn from the title, I'm confused. Landed on my coat on a really hot day (About 86°F ... why was I even wearing a coat???)

Moved from True Bugs.

An "easy" species, the medial sulcus of pronotum, combined with habitus and colour being diagnostic: Dufouriellus ater (common under bark).

Thanks for the ID, Boris!
Looks like a new one for the Guide, too. I see this is mainly a European species ... is it introduced here in North America, or a holarctic species?

common in California
This species is common in California's San Joaquin Valley. I find it under bark on grapes and pomegranates, and in old nuts on almonds. I have seen it eat Psocoptera, which are common wherever I see this pirate bug, and may be it's principal diet. The nymphs are bright red.

Doesn't look like the minute pirates of my acquaintance
Those pirates had broader shoulders and a white, more tapered look at the very back.

We will leave the coat question for another time. LOL.
