Explanation of Names
Megacyllene robiniae (Forster 1771)
robiniae = 'of Robinia' (refers to a host tree)
Size
11-28 mm(1)
Identification
Adult beetles are black with yellow transverse bands. The third band on the elytra is W-shaped.
Range
NS-FL west to ON & Great Plains(2)(3)
Habitat
Adults common on goldenrod in late summer and fall
Food
Larvae feed on Black Locust (Robinia pseudoacacia). Honey Locust (Gleditsia triacanthos) is not affected. Adults feed on pollen, particularly goldenrod (Solidago spp.).
Life Cycle
Eggs are laid in the fall. Newly emerged larvae hibernate under bark, tunnel in spring, making tunnels about 10 cm long and 6 mm wide, pupate late Jul/early Aug; adults emerge late Aug-Sep.
Larva & pupa
Remarks
Considered a serious pest of Black Locust; previously weakened or damaged trees are often killed by the larvae. Previously confined to the native range of Black Locust in the northeast, it has spread with the trees throughout the US and parts of Canada. Black Locust is used for reclamation and similar projects where trees are likely to be stressed and thus more vulnerable to damage.
