An inventory of wild-caught caterpillars, its food plants and parasitoids, has been going on for more than 34 years in Area de Conservación Guanacaste (ACG), a protected area of approximately 1200 km2 in northwestern Costa Rica.
When facing a flood, ants build rafts and use both the buoyancy of the brood and the recovery ability of workers to minimize injury or death
In areas across the southeastern United States, invasive "crazy ants" are rapidly displacing fire ants by secreting a compound that neutralizes fire ant venom, according to a new study from The University of Texas at Austin.
We have known and celebrated the strength of the tiny ant, but never really understood how it was achieved, until now. A new study from Ohio State University reveals that the real secret to the ant's legendary strength may lie in its tiny neck joint.
Aggression-causing genes appeared early in animal evolution and have maintained their roles for millions of years and across many species, even though animal aggression today varies widely from territorial fighting to setting up social hierarchies.
Male European honey bees are far more susceptible to a widespread fungal intestinal parasite than female members of the species, according to new research appearing in the January 17 edition of the open-access scientific journal PLoS ONE.
A group of scientists from the University of Mainz and the Senckenberg Museum of Natural History Goerlitz, headed by Susanne Foitzik and Bernhard Seifert, recently described a new slave-making ant species from the eastern USA.
Ants grow the size of their thoracic segments differently according to the specialized tasks they will perform as adults.
A new study provides seventeen records of the cuckoo wasp genus Cleptes from China, nine of which are beautifully colored new to science species.
We know more about wildlife this week, thanks to research by two Canadian teens.
The jack jumper ant (Myrmecia pilosula), known by other names including the jumping jack or hopper ant, is a species of bull ant that can be found in Australia. Its range includes Tasmania, New South Wales, and rural areas of Victoria. This species is unique in that its genome only holds on set of chromosomes, which is the lowest number of chromosomes that any animal can hold. Like other bull ants, this species can build nests under rocks or under dirt mounds. The jack jumper reaches an...
The inchman (Myrmecia forficate) is a species of bull ant that can be found in Australia, in a range that includes Tasmania and possibly southeastern areas of Australia. This species is gregarious, living in colonies like most other ant species, but it forages for food alone. Nests often go unseen and are typically found under rocks.Â It reaches an average body length of up to one inch long, the trait from which it received its common name. The inchman is both a scavenger and a...
A wasp is any insect of the order Hymenoptera and suborder Apocrita that is not a bee, sawfly, or an ant. The less familiar suborder Symphyta includes the sawflies and wood wasps, which differ from the Apocrita by having a broad connection between the thorax and abdomen. Also, Symphyta larvae are mostly herbivorous and "caterpillarlike", whereas those of Apocrita are largely predatory or parasitic. Most familiar wasps belong to the Aculeata, a division of the Apocrita whose ovipositors are...
The Bombyliids are a large family of flies with hundreds of genera. Their life cycles are not well known. Adults generally feed on nectar and pollen, thus are pollinators of flowers. They superficially resemble bees, thus are commonly called bee flies, and this may offer the adults some protection from predators. The larval stage are predators or parasitoids of other insect eggs and larvae. The adult females usually deposit eggs in the vicinity of possible hosts, quite often in the burrows...
The bumblebee is a flying insect of the genus Bombus in the family Apidae and a relative of the common honeybee. The bumblebee feeds on nectar and gathers pollen to feed its young. They are beneficial to humans and the plant world alike, and tend to be larger than other members of the bee family. Most bumblebee species are gentle. From this comes their original name: "Humblebee". Bumblebees are social insects that are known for their black and yellow striped bodies, a commonality among the...
