I would like to get back to the moth habit, but the pickings have been thin - a weekend travelling to visit kids (and rainy nights), a weekend home in Somerville, ordering a replacement blacklight bulb for my moth light. Anyhow, I went out to the Fells yesterday just to walk around and found these. They seem to be Jagged Ambush Bugs (Phymata sp.), but getting the ID closer than genus seems dubious with available materials.
