Arnold Arboretum, Boston: 2026-07-24

[Peter Loshin]

We went to Arnold Arboretum in Boston this afternoon, hoping to see Pipevine Swallowtail and hairstreaks. It was mostly sunny, warm and no wind when we got there at 3:30 and stayed for 2 hours. We went up to the top of Bussey Hill, where we saw:

2 Pipevine Swallowtail

1 Red-spotted Admiral

2 Monarch

3 Tiger Swallowtail

1 Sulphur (sp)

3 Azure (sp)

2 Black Swallowtail

1 Cabbage White

The Pipevine Swallowtails were fairly faded and worn, but still recognizable; the swallowtails and Admiral were chasing around the top of the hill. The Monarchs and Sulphur were nectaring on clover in a field just below the top of the hill.
