Asian Longhorned Beetles Characteristics
Asian Longhorned Beetles, Anoplophora glabrapennis, infest hardwoods like maples, willow, elm, birch, and sycamore. These insects first infested hardwoods in New York City, New Jersey, Chicago, Massachusetts, and Toronto, but have now spread across the United States.
IDENTIFYING CHARACTERISTICS
Asian Longhorned Beetles are shiny black beetles measuring from 1-1½ inches. Their shells have white blotched markings and their long antennae are banded black and white. Their legs have a distinctive blue sheen. They can be mistaken with many native Canadian species, most commonly the white-spotted sawyer (Monochamus scutellatus). Asian Longhorned Beetles can be detected in the environment by the uniformly shaped holes they leave in affected …show more content…
She can lay up to 100 eggs at multiple sites by depositing one egg at each site. The small, and white larvae hatch and begin chewing away at the vascular tissue to tunnel inside to the wood of the tree. Tunnels are formed throughout the wood as all the larvae eat the wood and grow. These tunnels inhibit the trees growth by not allowing it to properly transport water and nutrients. They pupate inside of these tunnels in April and May and finally, the adult chews out of the tree from late May to July.
IMPACTED SPECIES
Adult female Asian Longhorned Beetles have a dramatic impact on a variety of Hardwood tree species. The beetles have a parasitic relationship with twelve different identified species of trees throughout the United States. These host trees include, Ash (Fraxinus), Birch (Betula), Elm (Ulmus), Golden raintree (Koelreuteria), London planetree/sycamore (Platanus), Maple (Acer), Horsechestnut/buckeye (Aesculus), Katsura (Cercidiphyllum), Mimosa (Albizia), Mountain ash (Sorbus), Poplar (Populus), Willow (Salix)
(aphis.usda.gov). Signs of an Asian Longhorned Beetle infestation do not appear until 3-4 years after initial affliction. As a result, identification of infestations is difficult for foresters. Furthermore, Asian Longhorned Beetle related tree deaths have been observed in every state in which the affected trees
