Box Elder Bugs are Acer specialists, feeding exclusively on the samaras (seeds) of various maple species. Box Elder Bugs tend to create massive congregations in sunny spots to keep warm while feeding and are often considered a nuisance in such large numbers – especially when the days become colder and they seek refuge in my bedroom! But overall, they’re totally harmless.

Monochamus males have some of the longest “horns” of any Cerambycids here in the northwest. These antennae are used to “smell” for females and are often more than twice their body length.

This tiny (5mm) leaf beetle is common in moist forests throughout the Pacific Northwest west of the Rockies. They seem to be particularly fond of hanging out in Hydrophyllum flowers.

Callophrys augustinus “Brown Elfin” Lycaenidae
Glacier National Park, MT
June 20, 2014
Robert Niese
This is a pretty common butterfly here in Montana. You can easily recognize them by their Lycaenid shape and dull metallic-y brown color. These guys don’t have tails like the hairstreaks, but sometimes have a tail-like lobe on their hindwings.
Satyrium saepium “Hedgerow Hairstreak” Lycaenidae
Seeley Lake, MT

Robert Niese
An adorable coppery hairstreak that rears its young on our abundant Ceanothus velutinus, or Snowbrush, here in Montana. Snowbrush grows best in open, brushy areas like those created after a fire or in a clearcut. And where there’s Ceanothus you’ll find these adorable Hedgerow Hairstreaks.
Glaucopsyche lygdamus “Silvery Blue” Lycaenidae
Glacier National Park, MT
June 21, 2014
Robert Niese
As with many members of the Lycaenidae family (blues, coppers, and hairstreaks), the caterpillars of this species are tended by ants which provide the vulnerable larvae with protection in exchange for sugary “honeydew” which the caterpillars excrete from their backs. Check it out.

One of the most abundant molluscs on the open coast, and apparently one of the tastiest.
