The Aedes aegypti mosquito typically prefers humid climates, but it has gained a foothold in the arid southwestern U.S. by using manmade containers for breeding sites—in particular, flower pots and the saucers underneath them.
Indigenous cultures in Colombia have known for a long time that stings from the little fire ant, Wasmannia auropunctata, can cause corneal lesions. Medical doctors are just figuring it out.
By John P. Roche As average temperatures rise globally, the ranges of many species will be affected. Climate-induced shifts in the ranges of invasive species will be particularly important because […]
By John P. Roche Spotted wing drosophila (Drosophila suzukii), is an invasive fruit fly species from eastern Asia, first seen in the United States in 2008. The species is devastating […]
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 John P. Roche West Indian sweetpotato weevils (Euscepes postfasciatus) are costly pests of sweetpotato plants (Ipomoea batatas) in the Pacific, the Caribbean, and Central and South America. Entomologists in […]
By John P. Roche Male Japanese stag beetles (Prosopocoilus inclinatus) have battles to defend territories to earn the opportunity to mate with females. They use enlarged mandibles that look like […]
Beetles may play a more important role in pollinating orchids than originally thought, based on a new beetle trapped in amber 20 million years ago
By John P. Roche With more than 7,000 species globally, the katydids are the second most diverse group within the insect order Orthoptera, after the grasshoppers. Katydids are members of […]
