Spotted Tree Borer Beetle - (Synaphaeta guexi)

The pesky Spotted Tree Borer Beetle attacks trees at the larval stage, making sick trees sicker.

Staff Writer (2/5/2014): Eggs for the Spotted Tree Borer are laid by females on a variety of weakened trees like oak, maple, willow, apple, pear and poplar. Larvae hatch and begin tunneling into the bark and eventually the heartwood, leaving trails of frass (feces that resembles saw dust) in their wake. The tunnels break into the cambium tissue and this causes the tree to leak sap. Trees that were already weak can die. The beetles are also found in dead trees that may become firewood or furniture. Spotted Tree Borer adults emerge from the wood in spring or fall.

BUGFINDER: What Kind of Bug is This...

BUGFINDER allows for a quick search of the Insect Identification database by selecting primary color, secondary color, number of legs and the territory / state in question. If only one color is present on your insect, select it again as its SECONDARY color. Remember that the more details you can offer, the better your chances of finding a match. As a rule of thumb, six legs are typical for most insects whereas spiders generally have eight legs.
