	A Cooperative Agreement and the Implementation of the Endangered Species Act: How Extension Can Facilitate Stakeholder Involvement and Compliance This 4-page fact sheet provides a brief description of the Endangered Species Act and updated action pertaining to the endangered species issue. The goal of this publication is to provide brief but clear information about the legislation and current agreements around this issue that Extension agents can use to increase educated conversations. Written by Chandra Bowden, Alexa Lamm, Tracy Irani, and Sebastian Galindo, and published by the UF Department of Agricultural Education and Communication, May 2013. http://edis.ifas.ufl.edu/wc141
	*Eastern dobsonfly (adult), hellgrammite (larva) Corydalus cornutus* (Linnaeus) (Insecta: Megaloptera: Corydalidae: Corydalinae) (EENY414/IN987)** The eastern dobsonfly is one of our largest non-lepidopteran insects. Its larvae, known as hellgrammites, are the top invertebrate predators in rocky streams where they occur. Adult male dobsonflies are particularly spectacular because of their large sickle-shaped mandibles (jaws). This 4-page fact sheet was written by Donald W. Hall, and published by the UF Department of Entomology and Nematology, April 2013. http://edis.ifas.ufl.edu/in987
	Granulate cutworm, Feltia subterranea (Fabricius) (Insecta: Lepidoptera: Noctuidae) The granulate cutworm, Feltia subterranea (Fabricius) is the most commonly occurring cutworm in Florida, though it is rarely numerous enough to be a major pest. It is nocturnal through most of its life, and lacks distinctive features in the larval and adult stage, so it often is overlooked, and its activities and damage are not fully appreciated. This 4-page fact sheet was written by John L. Capinera, and published by the UF Department of Entomology and Nematology, May 2013. http://edis.ifas.ufl.edu/in997
	*Olive shootworm, Palpita persimilis* Munroe (Insecta: Lepidoptera: Crambidae)** Palpita persimilis Munroe (Lepidoptera: Crambidae) is a defoliator of olives and privet in South America. Examination of specimens submitted to UF-IFAS and FDACS-DPI prompted the discovery that the species has been established in Florida for many years, having been confused with two similar native species. The confusion parallels historical misidentifications in Peru. To date, all vouchered specimens in Florida with host information were found feeding on leaves of Ligustrum japonicum Thunb. (Japanese privet). This 6-page fact sheet was written by James E. Hayden and Lyle J. Buss, and published by the UF Department of Entomology and Nematology, May 2013. http://edis.ifas.ufl.edu/in995
	Palm Morphology and Anatomy Palms differ greatly from broadleaf (dicot) and coniferous (Gymnosperm) trees in their overall form and external structure (morphology) and in their internal structure (anatomy). Morphology and anatomy determine how palms grow, function, and respond to external and internal stress factors. This publication provides a basic understanding of how palms are constructed. This 4-page fact sheet was written by T. K. Broschat, and published by the UF Department of Environmental Horticulture, May2013. http://edis.ifas.ufl.edu/ep473
	Sabal palmetto: Sabal or Cabbage Palm The sabal palm, or cabbage palm, is native to Florida and coastal regions of North and South Carolina and Georgia, and is the state tree of both South Carolina and Florida. The name “cabbage palm” comes from its edible immature leaves, or “heart,” which has a cabbage-like flavor. This 5-page fact sheet was written by T. K. Broschat, and published by the UF Department of Environmental Horticulture, July 2013. http://edis.ifas.ufl.edu/st575
	*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. http://edis.ifas.ufl.edu/in996
	*Seedcorn maggot, Delia platura* (Meigen) (Insecta: Diptera: Anthomyiidae)** The seedcorn maggot is a polyphagous pest, affecting more than 40 different host plants. It is an important pest of germinating soybeans and corn, and also attacks a wide range of horticultural crops including beans, peas, cucumber, melon, onion, pepper, potato, and other vegetables. Seedcorn maggots damage newly planted seeds by feeding on seed contents, often leaving empty seed shells and preventing germination. Although usually no more than 2% of the seedlings get infested by this insect, 30% to 60% plant loss may occur in the field. This 5-page fact sheet was written by Harsimran Kaur Gill, Gaurav Goyal, and Jennifer L. Gillett-Kaufman, and published by the UF Department of Entomology and Nematology, July 2013. http://edis.ifas.ufl.edu/in1002
	*The Asiatic garden beetle Maladera castanea* (Arrow 1913) (Coleoptera: Scarabaeidae)** The Asiatic garden beetle has been a pest in the northeastern United States since the 1920s. Generally not as abundant or damaging as the Japanese beetle, this pest beetle is occasionally numerous enough to cause damage to turf, gardens and field crops, as well as simply being a nuisance. It’s discovery in Florida was not unexpected. This is the first report of this pest beetle in the lower southeastern U.S. coastal plain. This 3-page fact sheet was written by Paul E. Skelley, and published by the UF Department of Entomology and Nematology, April 2013. http://edis.ifas.ufl.edu/in992
