General information about
Locust Borer :
Feeds mostly on Black Locust Trees. Female chews or bores holes into the bark of a tree and lays one egg at a time. The pupae then bore further into the tree to develop into adults. They usually emerge late in summer.
These insects have a sweet tooth, they usually eat pollen and nectar, but can be found snacking on almost anything that tastes sweet. Creatures like these are known to cause "Widow Makers"; giant tree limbs that can break off from high above, sometimes crashing down on individuals while they sleep. To combat these insects you will mostly just need to keep your tree watered during drought and if it gets bad you can apply a single dose of Carbaryl. en.wikipedia.org wiki Carbaryl
