Thanks Sue!
Every night when i bike up to the Lab i have to swerve around several kinds of bugs that are crossing the road.
The first photo is of an unidentified millipede. According to the
Montana Field Guide there are 25 species of millipedes in Montana. Unfortunately this is an area that doesn't seem to be well researched. None of the 25 species have pictures or descriptions in their Guide. Millipedes usually feed on decaying plant matter. They add segments and legs as they mature (which may take two to five years). They can live for several years as adults. When disturbed they may release a defensive chemical. In the past I've found some that emit smells like almonds or lemon.
The second photo is an unidentified camel cricket from the family Rhaphidophoridae. They eat organic debris, insects and other small arthropods. These crickets do not chirp or sing, as they have no wings. They prefer moist areas and are often found in caves. Not sure what moist spots they are able to find in this dry summer.
The third photo looks to be an unidentified funnel weaver spider from the family Agelenidae. These spiders often build a funnel shaped web and wait inside the narrow end for prey to fall on their net. They are some of the fastest running spiders and will run out to catch and bite prey. I guess the males are more likely to go on a walkabout as they are not as successful staying in one spot.
