Photograph by Paul M. Choate, University of Florida. Friauf JJ. In Florida, areas such as trees, woodpiles, garbage facilities, and accumulations of organic debris around homes provide adequate food, water, and harborages for peridomestic cockroaches such as the American cockroach (Hagenbuch et al. Eurycotis floridana occurs in a limited southeastern range in the United States. Eurycotis floridana was originally described as Periplaneta floridana (Walker 1868), as well as the following synonyms: Eurycotis floridana has no official common name as is sanctioned by the Entomological Society of America, but is known by the common names Florida woods cockroach, Florida stinkroach, skunk cockroach, and palmettobug. The ootheca left behind by many species of cockroach is susceptible to parasitoids. The Florida woods cockroach looks remarkably similar to the female oriental cockroach (Blatta orientalis), and the two could be mistaken for each other by the casual observer. 2007). 1988. Florida Insect Management Guide for cockroaches, Abed D, Farin JP, Francois J, Brossut R. 1994. Male sex pheromone of cockroach, Farine JP, Everaerts C, Le Quere JL, Semon E, Henry R, Brossut R. 1997. Sciencing. Medical and Veterinary Entomology, 2nd edition: Cockroaches (Blattaria). This species can exhibit some directional control of the secretion and has variable spray distance, from as close as three centimeters to as distant as one meter (Robinson 2005). Regular inspections and treating their (hidden) resting spots are the best treatment for the American cockroach. The deposited ootheca contains water sufficient for the eggs to develop without receiving additional water from the substrate (Bell and Adiyodi 1981). [3] Tegmina (fore wings) are very short, extending just past the mesonotum (the dorsal plate just behind the pronotum), and hind wings are absent. Compared to other roaches, the Florida woods cockroach is relatively slow moving and not quick to run away from disturbance. It’s probably impossible to rid yourself completely of the palmetto bug. Pest Control 27: 44-45, Farine JP, Le Quere JL, Duffy J, Everaerts C, Brossut R. 1994. The Blattidae of North America North of the Mexican boundary.

Florida palmetto bugs also feed on cardboard, so throw out those old, damp boxes in the garage or the back of kitchen cabinets. The reason these roaches invade homes is to find water or food. However, the size of the cockroach makes it easier to see differences in the posterior structure of the body segments, most notably the rectal area. 1970 and Smith & Whitman 1992). Growing up to 2 inches in length, they’re not only remarkably large, but most active at night – providing ample and ongoing opportunities to scare you out of your skin. Tampa Bay Times. Biosynthesis of arthropod exocrine compounds. Chemical Defenses of Arthropod Exocrine Compounds. Nymphs: Eurycotis floridana nymphs are reddish brown to black in color. 1953.

Flick on a bathroom light and you won’t be able to miss the one skittering across your bathtub. Close up of terminal sclerites located posteriorly, note the symmetrical filaments, on an adult male Florida woods cockroach, Eurycotis floridana (Walker). The adults have well developed cerci and tooth-like projections at the edges of the dorsal segments that approach the cerci. Eggs within the ootheca take approximately 48 days to hatch at 30—36°C. For most Floridians, the American cockroach is the palmetto bug they really have to deal with. Outdoors, American cockroaches are found in moist shady areas such as hollow trees, wood piles, and mulch. The American cockroach (left), the Florida Woods cockroach (middle), and the Smokybrown cockroach (right).

The Florida woods cockroach or palmetto bug (Eurycotis floridana)[2] is a large cockroach species which typically grows to a length of 30–40 mm (1.2–1.6 in). The males are longer than the females because their wings extend 4 to 8 mm beyond the tip of the abdomen. Alabama Agricultural Experiment Station Bulletin 404: 118. The female deposits the ootheca near a source of food, sometimes gluing it to a surface with a secretion from her mouth.
