TUSTEN, NY — This Delaware skipper, which was spotted during the 2014 Upper Delaware BioBlitz at Ten Mile River, is a rare find for Sullivan County. Skippers are known for their fast “skipping” flight.

BioBlitzes are events at which scientists and other volunteers gather to collect, identify, and catalogue every living thing on a demarcated property in a 24-hour period, with the results made available to the public following the collection period, along with various workshops and talks. The 2016 Upper Delaware BioBlitz will return to the Ten Mile River site this weekend; for more information see pages 23 and 32.
