Reelfoot Lake hosts annual Butterfly Count on June 23

"(WEST) Please join Allan Trently, Stewardship Ecologist, Natural Areas Program and Bart Jones, Butterfly Expert Extraordinaire for the Reelfoot Lake Butterfly Count. Butterfly species and numbers will be counted and the data will be sent to the North American Butterfly Association. These counts allow amateurs and professionals alike to participate in the appreciation and conservation of butterflies.  The count leader is Bart Jones of Memphis. The first part of the count will take place around the Park’s visitor center where we typically see the rare Tennessee butterfly, the Broad-winged Skipper. From there we will count butterflies in and around the lake. In 2011 the very rare Bronze Copper butterfly was located. You are not expected to identify and count the butterflies but merely participate in learning about these insects and some of the plants that they use. The count typically ends around 5 p.m. but you may leave earlier if needed. Since we will be out in the sun for most of the day bring sun block and plenty of water. Wear sturdy shoes, bring a snack and binoculars if you have them, and dress appropriately for the weather. We will not go in the event of inclement weather. Meet at 9:30 a.m. CT at the Reelfoot Lake State Park visitor’s center at 2595 State Route 21E, Tiptonville, TN  38079 (visitor center 731-253-9652). Reservations are required: Contact Allan Trently at 731-512-1369 or at allan.trently@tn.gov no later than June 21st. If you need to call me on June 23rd call my cell at 731-234-4887"
