Asian Longhorned Beetle (Anoplophora glabripennis)
The Asian Longhorned Beetle, an invasive pest from China, was discovered in New York and Illinois in the 1990's. So far, the only method of control for Asian Longhorned Beetles requires removing and chipping infested trees, along with potential host trees, in the area where it is discovered. A well-informed public may be our best defense against this invasive species.

Asian Multicolored Lady Beetle (Harmonia axyridis)
One of our most common lady beetles, the Asian Multicolored Lady Beetle, is actually a native of Asia. Now well-established across North America, this hungry predator devours aphids and other soft-bodied insects in gardens and home landscapes.

How Do Fireflies Light?
Fireflies, also known as lightning bugs, use light signals to attract mates. A complex chemical reaction in the firefly's light organ produces light energy efficiently.
