![]() □ The mesquite bug (a different species from the giant mesquite bug) has a long proboscis that it uses to poke into mesquite fruits to get at their seeds, which can therefore disrupt reseeding, but this bug does not seem to do much damage otherwise. Leaf-footed bug in the genus Mozena, possibly a mesquite bug Mozena arizoniensis, subfamily Coreinae, family Coreidae. Identified by: Ed Bynum, Ph.D,Įxtension entomologist, Texas A&M AgriLife Research and Extension Center. □ The adult version of this leaf-footed bug looks quite different from the nymph in this photo. Leaf-footed bug, nymph (immature), Mozena obtusa, subfamily Coreinae, family Coreidae. Photographed and identified to family by: Afier Jinda. They are quite common in Australia and Indonesia. □ The large cross on the crusader bug gives it its alternate name of holy cross bug. Location: near Lake Chapala in Jalisco, Mexico.Ĭrusader bug, Mictis profana, subfamily Coreinae, family Coreidae. The nymph shown here could be a nymph of either the species Thasus neocalifornicus or Thasus acutangulus. □ The giant mesquite bug nymphs look different as they go through their development, and the nymphs of one species can look like those of another. Giant mesquite bug, nymph (immature), either Thasus neocalifornicus or Thasus acutangulus, subfamily Coreinae, family Coreidae. Identified by: .ĭeb says, “I thought it was beautiful, markings so striking.” Each antenna of the female (but not the male) have a flat, somewhat diamond-shaped disk. Its hemelytra (forewings) have a thicker part with yellow veining, and a more membranous part with much finer veining, as seen here. It can grow to nearly 2 inches (5 cm) long. □ The adult giant mesquite bug is a large bug. Giant mesquite bug, female, Thasus neocalifornicus, subfamily Coreinae, family Coreidae. Funny I’ve never seen one of these before, as I’ve lived in this house 12 years.” Identified by: .Ĭarol says, “I have a big old mesquite tree in the back yard. Their bright colors warn birds to stay away. □ The nymphs of this giant mesquite bug can give off a bad-tasting secretion to help protect them from enemies, such as birds. Giant mesquite bug, nymph (immature), Thasus neocalifornicus, subfamily Coreinae, family Coreidae. Location: Fortin de las Flores, Veracruz, Mexico. This is why scientists use scientific names instead, so there is no confusion which species they mean. □ Several species go by the common name of giant mesquite bugs. Giant mesquite bug, nymph (immature), in the genus Thasus, possibly a color variation of Thasus acutangulus, subfamily Coreinae, family Coreidae. Order Hemiptera: the true bugs - Examplesįamilies represented - (current page): It’s always possible that we made a mistake, however, so if you see a misidentification, please contact us and we will correct it. Treatment can provide rapid knock-down of fruit-damaging populations, but reinfestation can occur as long as large numbers of the bugs are actively moving into orchards to feed or seek sheltered overwintering sites.*** Note: does its best to include correct identifications of insect photos. When problems are detected, spot or border treatments are preferable to entire orchard sprays. Therefore, insecticides should not be used unless necessary to prevent substantial fruit damage. However, repeated insecticide applications have been shown to quickly create resistance and will dramatically reduce natural enemies. Insecticides can provide quick and effective control of piercing-sucking bug pests when their use is targeted for substantial populations at a susceptible stage of fruit development. Most potential problems can be reduced by appropriately managing or removing the alternate hosts. SYMPTOMSīoxelder bugs use plant hosts in addition to fruit trees for feeding, reproduction, and overwintering. They're bright orange-red when first hatched, and the black markings appear when half grown. Nymphs resemble small adults without wings. They're typically laid on leaves, in crevices of bark, and on other surfaces. THe underside of the abdomen is striped in red and gray.Įggs are small, oval, and red. Their bodies are gray to black, with distinct red lines on the thorax and wing coverings. BIOLOGYĪdults are 1/2 inch long, elongated, oval, and flattened on top. The major concern over boxelder bugs is when they congregate on the sides of or enter into buildings and are a nuisance to people. They generally do not injure ornamentals. Large populations generally develop only on female (seed-bearing) boxelder trees and relatives, where they feed primarily on the developing seeds. They can cause fruit injury similar to that of late-season stink bug feeding, such as dimples, scarring, and fruit deformation. ![]() Boxelder bugs are generally not pests of great concern in fruit orchards however, adults can damage fruit when large numbers migrate into orchards in search of overwintering sites in the late summer and fall. ![]()
