Pensoft Publishers A mysterious parasitoid wasp was found in the Böhmerwald (Northeast Austria) and reared in the garden of the amateur entomologist Ewald Altenhofer of Gross Gerungs municipality, Austria. The parasitoid was identified by Kees van Achterberg, senior researcher at the Naturalis Biodiversity Center in Leiden, the Netherlands, as the rare Seleucus cuneiformis. It is the first time that a tip of its biology was discovered. The study was published in the open...

Harvard University scientists have determined some bees brace themselves against wind and turbulence by extending their hind legs while flying. Wind is a universal part of life for all flying animals, Assistant Professor Stacey Combes said. Yet we know remarkably little about how animals navigate windy conditions and unpredictable airflows, since most studies of animal flight have taken place in simplified environments, such as in still air or perfect laminar flows. Combes and Robert Dudley...

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...

A caterpillar is the larval form of a lepidopteran (a member of the insect order comprising butterflies and moths). Caterpillars are characterized by their long segmented bodies and many sets of "legs". They eat voracious leaf eaters and grow rapidly, During growth the caterpillar will shed its skin four to five times before pupating into its adult form. Caterpillars have six true legs (being hexapods) on the thorax, up to four pairs of prolegs on the middle segments of the abdomen, and...

PHOTO CAPTION: Eriothrix rufomaculata (Photo taken by Keith Edkins) The tachinid flies (family Tachinidae) are by far the largest and most important group of insect parasitic flies, with over 1300 species in North America. It is a diverse group with some resembling drab houseflies and others brilliantly colored. All species are parasitic in the larval stage, and many are important natural enemies of major pests. Many species of tachinids have been introduced into North America from...

Apocrita is a suborder of insects in the order Hymenoptera. The Apocrita include wasps, bees and ants, and are comprised of many families. They include the most advanced Hymenoptera and are distinguished from the Symphyta by the narrow waist joining two segments of the abdomen. The ovipositor of the female either extends freely or is retracted, and is converted into a sting for both for defense and for paralyzing prey. Larvae are legless, and may feed either inside a host or in a nest....
