July 19, 2025 – October Mountain

We took the long trip out to October Mountain in Washington, MA to see what was flying out there. Often there are several species that we just don’t get down our way. We met up with a couple friends and one new friend who had come out from Colorado with a want list of lifers he wanted to see so we were determined to find some of those for him.

The day was super nice with full sun and highs in the upper 70’s so it was optimal weather for butterflies.

We started off real strong, finding a Harvester that was super large! This thing was 2-3x the normal size of a Harvester, and it happened to be on his life list needs.

The species seen were typical for the area after that with several Fritillaries, mainly Great Spangled and one or two Atlantis Fritillaries.

Other species we saw were Dun Skippers, Delaware Skippers, an Eastern Comma, several Baltimore Checkerspots, Appalachian Browns, Northern Pearly Eyes, Red-spotted Purples, Mulberry Wings, Pecks Skippers, Dion Skippers (photo above), etc.

In all, I think he saw 6 lifers which was a huge success!

A great day with great people.

I will “end” this post with a shot of a Chestnut-sided Warbler. I am not much of a bird photographer…
