Leucospilapteryx venustella (Clemens) (Lepidoptera: Gracillariidae) is a small, mostly light brown moth that during its larval stages creates mines in the leaves of plants in the family Asteraceae. Feeding damage by the early instars is characterized by serpentine mines that are expanded by later instars to form tentiform or blotch mines.

Scarlet-bodied wasp moth, Cosmosoma myrodora (Dyar) (Insecta: Lepidoptera: Arctiidae)
The scarlet-bodied wasp moth, Cosmosoma myrodora (Dyar), is a beautiful native insect. Because of its striking adult coloration, including a bright red thorax and abdomen, and transparent wings patterned with black, this moth immediately stands out in Florida landscapes. Larval feeding is restricted to two native plants in the genus Mikania, family Asteraceae. This 5-page fact sheet was written by Diego Moscoso, Rodrigo Diaz, and William A. Overholt, and published by the UF Department of Entomology and Nematology, May 2013.

Tropical Soda Apple Leaf Beetle, Gratiana boliviana Spaeth (Insecta: Coleoptera: Chrysomelidae: Cassidinae) (EENY543/IN974)
Tropical soda apple is a prickly shrub native to South America that is a major problem in pastures and conservation areas. So a multi-agency program supported the rearing, distribution, and release of more than 250,000 tropical soda apple leaf beetles across Florida from 2003 to 2011. This 4-page fact sheet was written by Rodrigo Diaz, William A. Overholt, Ken Hibbard, and Julio Medal, and published by the UF Department of Entomology and Nematology, January 2013.

Classical Biological Control of Tropical Soda Apple with Gratiana boliviana (ENY865/IN971)
Tropical soda apple is a prickly shrub native to South America. First reported in Glades Co., Florida in 1988, it later spread to Georgia, Alabama, Louisiana, Texas, Mississippi, Tennessee, North Carolina, and South Carolina. It is a major problem in pastures and conservation areas. Negative impacts of tropical soda apple include reduction of cattle stocking rates, competition with native plants, and the costs associated with its control. Dense thickets of the weed also can disrupt the movement of wildlife. This 4-page fact sheet provides a summary of the major steps of the successful biological control program against tropical soda apple in Florida. The article covers the importance of the weed, identification and biology of the biological control agent, rearing and release efforts, establishment and impact, and efforts to communicate the outcomes of the program to stakeholders. Written by R. Diaz, J. Medal, K. Hibbard, A. Roda, A. Fox, S. Hight, P. Stansly, B. Sellers, J. Cuda and W. A.
