What could a little bug do to a big tree? Kill it

EAB larvae are often found boring galleries near the bases of branches as this location provides them some protection from woodpecker predators. EAB larvae cause damage to ash hosts by boring galleries in the sapwood. Larvae bore galleries in the wood, pupate within these gallery spaces, and emerge through holes in the spring. Here, an adult is ready to emerge and can be seen within the wood tissue. USDA/APHIS/Gerald Wheeler
