June update - Invertebrates

I saw quite a lot of invertebrates (butterflies, beetles, flies, bees, spiders, and one millipede) in June.  Most are not yet properly identified.  I will try to do so later in the field season.  Until then, just enjoy the diversity of invertebrates seen here in Gunnison National Forest.
