On July 30, volunteers with the North American Butterfly Association conducted their annual July butterfly count at Duke Farms.
A few highlights/observations from the field report from Michael Gochfeld, Ph.D. (Rutgers University):
- "We tallied 31 species which is about average and 1066 individuals, also average.
- We had two new species: Cloudless /sulphur and Swarthy Skipper
- We had several new high counts: Black & Spicebush Swallowtails, Gray & Red-banded Hairstreaks and summer azure.
- The Greatest biodiversity was in areas: Community Gardens, Haybarn Meadow, and Dutchess Farm.
- Surprisingly we didn’t record any Sachems.
- 30 Painted Ladies was almost a record, and there were no American Ladies.
- Overall an interesting count, mostly average or typical with respect to species and numbers. A dramatic improvement over a month ago.
- Duke has managed its meadows intensely for several years, aiming for native wildflowers and grasses."
