Tippecanoe Butterfly Encounter Results


Silver Spotted Skipper

The results of the Tippecanoe Butterfly Encounter are in and there were few surprises. The count is consistently on the third Saturday in July. However, the seasonal weather patterns and conditions during the count affect what we find. 2015 has been noted for the cool, wet weather in Indiana. These conditions will delay development and shift the peak flight of some species to later in the season. This year we did not see a buckeye butterfly, but I expect to see some by late summer. 2012 had warm dry conditions for spring and summer and we saw a couple dozen. In 2013, Eastern Tailed Blues were the third most common butterfly (behind cabbage white and silver-spotted skipper) but this year we spotted only one. Monarch populations were not as high as their peak, but more than double the 2014 count. This correlates with a 2X increase in the overwintering population in Mexico. We saw more Monarch caterpillars than adults. The caterpillars were commonly feeding on the milkweed flowers. A larger generation is in the works. Others have reported increased sightings of monarch adults and caterpillars. Perhaps the population is on the rebound? The cabbage white population was not as robust as in previous years. This year, we counted more silver-spotted skippers than any other.
