Love 44 IRCF REPTILES & AMPHIBIANS CONSERVATION AND NATURAL HISTORY Copyright © 2016. Kenneth L. Krysko. All rights reserved. WWW.IRCF.ORG/REPTILESANDAMPHIBIANSJOURNAL T he Tokay Gecko, Gekko gecko (Linnaeus 1758), is native to southeastern Asia. It has been introduced to many areas around the world (Kraus 2009), including Florida, USA (Barbour 1931; Krysko et al. 2011a, 2011b). In Florida, it has been intentionally introduced by animal dealers (Meshaka et al. 2004), by residents to control cockroaches in homes (Wilson and Porras 1983), and accidentally via escaped pets. In southern Florida, Gekko gecko has been documented consuming mostly beetles, roaches, and moths (Meshaka et al. 1997a, 2004a), but it is also known to prey on the Woodslave, Hemidactylus mabouia (Moreau de Jonnès 1818; see Meshaka et al. 2004a) and Eastern Corn Snake, Pantherophis guttatus (Linnaeus 1766; see Love 2000; Fig. 1). Herein, we augment our knowledge regarding the diet of G. gecko in Florida to include the native Carolina Wren, Thryothorus ludovicianus (Latham 1790), and nonnative Cuban Treefrog, Osteopilus septentrionalis (Duméril and Bibron 1841). Photographs of these two new events, as well as for the Pantherophis guttatus (cited above), were deposited as vouchers (UF-Herpetology 150221, 177230–177233; Figs. 1–3) in the Division of Herpetology, Florida Museum of Natural History, University of Florida. All three observations occurred on the side of a house, approximately 0.61 km southwest of State Road 80 and the Hendry County line, Alva, Lee County (26.70404, -81.56775; WGS84). Fig. 1.
