Latest Hymenoptera Stories
That smaller islands will typically sustain fewer species than large ones is a widespread pattern in nature. Now a team of researchers shows that smaller area will mean not only fewer species, but also shorter food chains. This implies that plant and animal communities on small islands may work differently from those on large ones.
Altruistic workers in social insect colonies – such as ants, bees and wasps – are more likely to be female, because their maternal instincts make them better at caring for the queen's offspring.
Queen bees convey honest signals to worker bees about their reproductive status and quality, according to an international team of researchers, who say their findings may help to explain why honey bee populations are declining.
Scientists originally believed that ants and bees were more distantly related, with ants being closer to certain parasitoid wasps. But new research shows that ants and bees share a much closer relationship.
Although bees are capable of defending themselves using their painful stings, the life of a honey bee is fraught with dangerous predators that seize them from the sky and wait to ambush them on flowers.
Colonies of rock ants (Temnothorax albipennis) need to find ideal homes for the safety and productivity of the queen mother and all of her offspring.
Because their loyalty can be bought, mercenary soldiers are notoriously unreliable and may turn against their employers before moving on to the next dirty job. A new report shows that fungus-farming ants are much different, however.
Like cuckoos, honeyguides are parasitic birds that lay their eggs in other birds' nests and dupe them into raising their young.
A University of Utah biologist has identified 33 new species of predatory ants in Central America and the Caribbean, and named about a third of the tiny but monstrous-looking insects after ancient Mayan lords and demons.
Ants keep a collection of ‘snapshots’ taken close to the nest so they can find their way home from unfamiliar locations.
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...
