Female beetles remain with their brood until they mature. Newly emerged adult beetles mate with their offspring before leaving the gallery. Flight activity apparently occurs throughout the year, with higher activity in March. Mouthparts are for chewing. This beetle attacks 126 plant species including pecan, peach, plum, cherry, persimmon, golden raintree, sweet gum, Shumard oak, Chinese elm, sweet potato and magnolia.
Infestations start with a female beetle boring in to a twig, branch or trunk of a host plant.
Host material can range from approximately 0.8 inch to 11.8 inches in diameter. This beetle will attack seemingly healthy trees. Attacks generally occur on the trunk of the host plant. Immature stages can be found by splitting open infested twigs and branches. Adults can also be obtained this way, reared from infested wood or trapped using a flight intercept trap - a pane of glass with a trough underneath it baited with ethanol.
