Salvato and Holly L. Salvato 1765 17th Ave SW, Vero Beach, FL 32962 [email protected] The Florida leafwing, Anaea troglodyta floridalis F. Johnson and Comstock (Nymphalidae), occurs locally within the pine rocklands of southern Florida. Hennessey and Habeck (1991) and Worth et al. (1996) described many aspects of A. t. floridalis natural history. Salvato and Hennessey (2003) and Salvato and Salvato (2010) also discussed A. t. floridalis ecology and provided a review of known predators for the species. Over the past several years we have conducted intensive monitoring of A. t. floridalis in the Long Pine Key region of the Everglades National Park (Miami-Dade County, Florida), to document various mortality factors on the immature stages of the species. On several dates between 27 November and 11 December 2010 we followed the development of an early instar A. t. floridalis larva on its hostplant, pineland croton (Croton linearis). Throughout this period an orb spider (Neoscona, most likely, N. arabesca Walckenaer) (Fig. 1) was observed on an adjoining branch in close proximity to the larva. On 17 December 2010 we relocated the larva in the webbing of the spider (Fig. 2), Fig. 1 An orb spider (Neoscona, most likely, N. arabesca) in Long Pine Key, Everglades National Park on 27 November 2010 (Pho- apparently predated. to: H. L. Salvato). This individual clearly wandered too close to the web, getting entangled and consumed. However, on other occasions we have observed A. t. floridalis larvae and orb spiders on the same pineland croton, without predation. Acknowledgement We thank Dr. G.B.
