2013 Long Point Butterfly Count

On a mostly sunny and warm July 6th the Norfolk Field Naturalists held the 22nd Long Point Butterfly Count.

Most groups commented on the relatively low numbers of butterflies but we did manage to come up with a respectable 2186 individuals of 49 species (average of 2572 and 49 respectively since 1992). The species total doesn't include the single larvae of Giant Swallowtail or the White Admiral form that is considered the same species as Red-spotted Purple. The North American Butterfly Association simply uses the common name Red-Spotted Admiral to refer to both subspecies.

Highlights and Lowlights:

New for the count: 3 American Snout, bringing us to 77 species all time
1004 Edward's Hairstreaks is a new count high (previous was 73)
2 Gray Comma passes previous record of 1
12 Crossline Skippers ties the previous high
2 Striped Hairstreaks are the first since 2007
4 Monarch beats previous record low of 5 set in 2002 (average of 51 since 1992)
1 Question Mark ties record low

  1. Adam, thanks for sharing. Its interesting to read what is showing up in other counties. Its amazing to read that Edwards Hairsteaks are more abundant than Cabbage Whites! Things are a little more sparse this year it seems. In particular, where are all the Monarchs? Its front page news here in Windsor.

  2. I think the theory is that not too many Monarchs wintered in Mexico this past winter, and then the late spring meant there wasn't much milkweed for the subsequent generations that wanted to move north. Hopefully they are able to recover.
