Pillbug, Roly-Poly, Woodlouse Armadillidium vulgare (Latreille) (Malacostraca: Isopoda: Armadillidiidae)

Figure 1. Pillbug, Armadillidium vulgare (Latreille), rolled into a ball. The roly poly is an isopod, a type of non-insect arthropod also known as a terrestrial crustacean. It is called a roly-poly because it rolls into ball when disturbed. This defensive behavior also makes it look like a pill, which is why it is sometimes called a pillbug. In Europe, the name woodlouse is used for both roly polies and sowbugs because these arthropods are frequently found under logs. Roly polies are nocturnal, though they may be found during the day in the soil or under debris. They are beneficial in the garden or landscape.

Byron, and Jennifer Gillett-Kaufman and published by the UF Department of Entomology and Nematology, August 2015. (Photo by James Castner, University of Florida)

Black Scale Saissetia oleae (Olivier, 1791) (Insecta: Hemiptera: Coccoidea: Coccidae)

Credit: Lyle Buss, University of FloridaThe black scale is an important pest of citrus and olive trees. Originally from South Africa, this scale is now distributed worldwide. In Florida, black scale is found on citrus, cultivated olive, avocado, and many popular landscape plants. It is likely that black scale, like many invasive pests, was imported to the United States on infested nursery plants. Based on their small size and the unique life history of scale insects, these insects are difficult to detect and control. This 4-page fact sheet was written by Morgan A. Byron, Jennifer L.

Reeves, University of FloridaBroad-headed bugs belong to a well-known but relatively small family of plant-feeding true bugs, usually seen feeding on the foliage and flowers of leguminous and graminaceous crops. Leptocorisa acuta (Thunberg) can be found on many crop plants in the family Poaceae (grasses), especially rice, and is a reported pest of economic significance in rice-producing countries like India, Australia, and China.
