I saw a bunch of these bright moths swarming the garage at work. This picture was taken in July. These guys were hanging from a roof. I imagine the little one is the male? Thanks,

These are mating Oakworm Moths in the genus Anisota. The World’s Largest Saturniidae Site lists three members of the genus in Michigan and they can be difficult to tell apart. We believe these are either Anisota senatoria, the Orange-Tipped Oakworm Moth or Anisota virginiensis, the Pink-Striped Oakworm Moth. More information on this genus can be located on BugGuide. Yes, the smaller darker moth is the male.
