Flea beetle
From Wikipedia, the free encyclopedia
Flea beetle is a general name applied to the small, jumping beetles of the leaf beetle family, Chrysomelidae. They make up the tribe Alticini, which is a part of the subfamily Galerucinae, though they were historically classified as a subfamily in their own right.
The adults are very small to moderate sized beetles, having the morphological characteristics of all leaf beetles, but having the hind femora (singular femur) greatly enlarged. These enlarged femora allow for the springing action of these insects when disturbed. Flea beetles can also walk normally and fly. Many flea beetles are attractively coloured.
In adverse weather conditions (rain, for example) some flea beetles seek shelter in the soil. At least a few species (Phyllotreta cruciferae and P. striolata) prefer warm, dry weather.
Adult flea beetles feed externally on plants, eating the surface of the leaves, stems and petals. Under heavy feeding these holes may coalesce into larger areas of damage. Some larval flea beetles are root feeders (Phyllotreta spp.).
Flea beetles may be beneficial or may be pests, depending on the species. Many major agricultural crops are attacked by flea beetles, including various cruciferous plants such as mustard and rape (particularly canola in north western North America). Numerous garden plants are also subject to flea beetle feeding, such as flowers of Gardenia and Rothmannia by Altica spp. Other flea beetle species are beneficial, feeding on undesirable plants. A few species have even been introduced to various locations as biological control agents against some weeds. One important example is in the control of leafy spurge, an invasive weed in the United States. Flea beetles of the genus Aphthona have been successfully introduced to control this plant. |
