Giant Mesquite Bug
The giant mesquite bug (''Thasus neocalifornicus'') is an insect of the order Hemiptera, or the "true bugs". As a member of the family Coreidae, it is a leaf-footed bug. As the common name implies, it is a large bug that feeds on mesquite trees of the American Southwest and Northwestern Mexico. Life cycle ''Thasus neocalifornicus'' is univoltine, meaning they have one generation of offspring annually. From January through July, the nymphs develop from first-fifth instars. Each subsequent instar more closely resembles an adult than the last. They often prefer the undersides of leaves and migrate towards the base of mesquite trees in summer. Adults lay eggs on the trees from August until October. Only the eggs survive the winter season. Distribution ''Thasus neocalifornicus'' inhabits the Sonoran Desert from southwestern Arizona to the Mexican state of Baja California Sur and can be plentiful depending on the season. They have also been found in the state of Texas and the Mexican ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
