Videos of Leafcutter Ants Show Their Division of Labor


Leafcutter ants may be the world’s first farmers. They basically collect leaves, bring them into their nests, and then eat the fungus that grows on the leaves. Now scientists have videotaped never-before-seen views of leafcutter ants at work processing leaves and growing their food supply. In a paper published in the journal Royal Society Open […]

Large New Species of Harvestman Only the Second in Its Genus


Harvestmen are arachnids that are often mistaken for spiders. However, they are not even in the same order — spiders belong to Araneae, while harvestmen belong to Opiliones. In the U.S., harvestmen are often called “daddy-longlegs” and are sometimes mistaken for cellar spiders in the family Pholcidae. A newly discovered species, however, does not resemble […]

Bed Bugs that Feed Are More Likely to Survive Pesticide Exposure


By Josh Lancette Many studies have been done on how effective certain pesticides are when they are applied to bed bugs. However, most have not allowed the bed bugs to take a blood meal after being exposed to pesticides, which can change the mortality rates, according to an article in the Journal of Medical Entomology.

Suffering for Science: Why I Have Insects Sting Me to Create a Pain Index


By Justin Schmidt Over the past 40 years (but in reality since I was five years old), I’ve been fascinated with insects and their ability to sting and cause pain. In graduate school, I became interested in why they sting and why stings from such tiny animals hurt so much. To answer these questions, we […]

Four New Fungus Gnat Species Found in Northern Scandinavia


Four new fungus gnat species have been described in a paper published in Biodiversity Data Journal. The species were collected from mires and old-growth forests of Finnish Lapland between 2012 and 2014. “These four species are really interesting because they are rather distant to other known members of the genus Boletina,” said Dr. Jukka Salmela, […]

A noted problem insect in the United States for more than a century, the squash bug continues […]

Researchers Find Hundreds of Arthropod Species in U.S. Homes


The first study to evaluate the biodiversity of arthropods in U.S. homes has found that humans share their houses with more than 500 different kinds of arthropods such as insects, spiders, mites, and centipedes. “This was exploratory work to help us get an understanding of which arthropods are found in our homes,” said Matt Bertone, […]

Ticks that Transmit Lyme Disease Reported in 48.6% of U.S. Counties


By Hannah Foster Lyme disease is a potentially debilitating disease caused by the bacterium Borrelia burgdorferi. The disease is spread to humans by two tick varieties: the blacklegged tick (Ixodes scapularis), which is responsible for most cases of Lyme disease in the United States, and the western blacklegged tick (Ixodes pacificus), the culprit for cases […]
