Hunterdon County, NJ

9:30-11:00. Walked the loop at the northern part of the property. The trail map on the N j Trails website shows this area to be a mix of forrest and fields, but I found the “fields” to be a mixture of woods, forrest and, for variety, areas with lots of trees. Finally found one smallish opening with blooming bergamot. All the action was there, a swallowtail mass gathering with no social distancing observed.

Home garden, Fredon Twp.
Sussex County, NJ

Mostly sunny, high in upper 80s. One Tiger Swallowtail was a released female, from a caterpillar found in the yard on Black Cherry. A Spicebush was expected to emerge the same day, but instead we got a parasitoid wasp, likely Trogus pennator, which specializes in swallowtail caterpillars. But a Meadow Fritillary, rare to see in our garden, made up for the disappointment.

3-5 pm. Sunny to partly cloudy but due to time of day many areas in shade, which the hairstreaks seemed to prefer. A dedicated Red-banded Hairstreak survey following the earlier count of 19. That count was on only one section of trail, so I wanted to do a full survey throughout the meadows. Even with the dedicated effort I was quite surprised by the result. I saw none nectaring.

There has been a nice variety of butterflies in the garden the past few days. I think I had a flyby American Snout as well. It didn't land. I did have a caterpillar on my Hackberry sapling last year. Maybe I will get lucky again.

Thistles, Bee balm, various mints, composites and Loosestrife are doing much better than Buddleia and Joe Pye this year.

11:30 to 3:00. Sunny; temps in mid-80s. The bulk of the Tiger Swallowtails were in the fields off the upper left parking lot in main park section, and the fields at the end of Cherry Street. In both cases swallowtails were hungrily swarming on Monarda and Blazing Star. I've never seen so many dark Tiger females; a conservative estimate would be between 15 & 20% of all Tigers counted.
