Long Point Butterfly Count

Report by: Adam Timpf This year's Long Point butterfly count was held on July 5th, 2014. We had an uptick in participation this year with 31 observers and had all parts of the circle well covered. Despite this, and nearly ideal weather conditions on the day, most groups commented on the lack of butterflies. With everyone's hard work we still managed to find 3731 individuals of 52 species. If it wasn't for the 2108 Edward's Hairstreaks, our individuals total would be far under the long term average of 2622 individuals. 52 species is slightly above the long term average of ~49. Notable sightings: 2108 Edward's Hairstreak. This will likely be a new North American high count surpassing the 1004 record set by our count last year. 71 Banded hairstreak. New count high. Previous high was 57 in 2006. 1 Meadow…

Effects of Habitat Fragmentation on Swallowtail Butterflies

By Jenna Siu, Department of Biology, University of Western Ontario Jenna Siu is a M.Sc. Candidate in the Environment and Sustainability Collaborative Program, Department of Biology, The University of Western Ontario, London, Ontario Research was done under the supervision of Dr. Daria Koscinski and Dr. Nusha Keyghobadi. The following is a brief summary of Jenna's research work. Background: In southern Ontario some of the most threatened habitats occur in the Carolinian Zone, where major portions of prairies, savannahs and forests have been destroyed. These changes to the natural landscape have caused habitat loss and fragmentation; the breaking up of habitat into smaller patches creating more edges, or the boundary between two land cover types. Habitat fragmentation has been shown to have harmful impacts on native populations (e.g. the Acadian Flycatcher, the American Badger, and the Grey Ratsnake). To understand how…
