A scanning electron micrograph shows an engorged female Ixodes angustus tick with a male I. angustus attached to its underside in typical feeding mode—a case of hyperparasitism presumed uncommon in the species.
First encountered in the United States in Pennsylvania in 2014, the spotted lanternfly had spread to New York, Delaware, and Virginia by early 2018. The invasive insect threatens Tree of Heaven as well as grapes, hops, and fruit trees, and it has a penchant for hitchhiking. Anyone sighting spotted lanternfly is urged to report it to their state agriculture department or local extension office.
American cockroaches show different individual "personalities" that relate to their fleeing behavior and preference for venturing into open spaces or remaining close to walls or other objects. A new study suggests these differences could be an evolutionary benefit for their collective fleeing response.
What would happen if you asked a machine to come up with new common names for insects? A scientist and her neural network find out.
A common gardener's tip suggests that the imported cabbageworm butterfly (Pieris rapae, also known as the "cabbage white") can be deterred with an artificial mimic. But does it really work?
A new study in the Journal of Medical Entomology offers the best look yet at the Haller's organ, a small sensory pit on the forelegs of ticks that they use to detect heat and chemical odors emitted by potential hosts.
This new documentary explains what makes entomologists tick.

By John P. Roche Blister beetles produce cantharidin, a 10-carbon isoprenoid molecule that is highly bitter and is toxic to most animals. Because cantharidin is so bitter, it discourages predators, […]
By Adrian Smith, Ph.D. Trap-jaw ants, with their spring-loaded jaws and powerful stings, are among the fiercest insect predators, but they begin their lives as spiny, hairy, fleshy blobs hanging […]

Think for a moment about the date May 15, 2003. Any idea what you were doing that day? (It was a Thursday.) And can you think of anything that you’ve […]
