OFNC’s 16th annual butterfly count

team

The butterfly count is an annual OFNC event organized this year by Jeff Skevington. Working in groups or alone, participants patrol the same location – a 24-km diameter circle centred on Manion Corners – each year from about 9 a.m. to about 4 or 5 p.m. Data are submitted to the North American Butterfly Association.

Ideal habitat for a large number of butterflies, the count site includes both alvar and swamp.

This year, the count got off to a delayed start when high winds on Saturday caused the organizers to postpone the event hoping for better conditions on Sunday, 3 July. They were rewarded with a sunny morning, with wind speeds of 7-25 kph, although it became windier later in the day. By 3 p.m., light rain was falling, ending the count early. A potluck dinner followed.

Many of our veteran area leaders were away this year, so coverage was below normal. The largest group included both experts and enthusiastic newbies: Jeff Skevington, Angela Skevington, Alexander Skevington, Rob Ellis, Li-Shien Lee, Derek Ellis, Julia Ellis, Celeste Cassidy, Elizabeth Gammell, Reni Barlow, Juliet McMurren, Gabriel McMurren, Sarma Vishnubhatla, and Lakshmi Vishnubhatla. Well know local butterfly expert Rick Cavasin covered two other areas with help from Ian Whyte.

The results were very good for the two groups that were out. Wetlands were dry as a result of the drought conditions in our area, so Sedge Skippers and related fauna were absent or not detected.

According to Jeff, “The Delaware Skipper is increasing its range and moving north. They were rare in our area a few years ago and are now regular on counts (you can see the change over time on the summary count sheet). The others are all regularly observed species.”

Thanks to Sarma Vishnubhatla for the photos of the participants above and to Reni Barlow for the gallery of butterfly photos below (be sure to click on them for a better view)!
