McLennen Park, Arlington and Horn Pond Mountain Woburn 2025-07-15

[Peter Loshin]

McLennen Park in Arlington was constructed on an old landfill, and today comprises soccer fields and other recreational areas -- as well as a large unmowed hill with various invasives (including phragmite grass) as well as some milkweed and other natives sprinkled in. There is also a body of water, where one can often see a Great Blue Heron (as I did today).

Lisa recently suggested that there might be butterflies on the hill, so I went to take a look today, and I saw:

6 Broad-winged Skipper

2 Monarch

2 Sulphur

5 Cabbage White

The Broad-winged Skippers looked pretty fresh.

Then, I went over to HPM, where I saw:

1 Northern Cloudywing (see below for photo, I'm not 100% on that ID)

3 Cabbage White

8 Eastern Tailed-blue

8 Northern Broken Dash

2 American Copper

2 American Lady

2 Red Admiral

2 Gray Hairstreak

1 Pearl Crescent

1 Sulphur

1 Little Wood Satyr

1 Black Swallowtail

1 Wild Indigo Duskywing

1 Common Buckeye

Also,

1 Bumblebee Clearwing
