Male spinner. Isonychia ?

Yes, it would appear to be. There are (at least) three Isonychia species recorded from Maine, I. bicolor, I. georgiae, and I. obscura. Although the greatest statistical likelihood would be I. bicolor, reliable identification to species requires microscopic examination of male imago genitalia.

Luckily, we have a mayfly entomologist actively participating on this forum, who is qualified to make such an identification, if sent a preserved specimen. See this thread.
Best regards,

They fasten red (crimson red) wool around a hook, and fix onto the wool two feathers which grow under a cock’s wattles, and which in colour are like wax.
