Sphecius speciosus, the eastern cicada-killer wasp, [1] is a large, solitary digger wasp species in the family Bembicidae. [2] They are so named because they hunt cicadas and provision their nests with them.
The Asian giant hornet is intensely predatory; it hunts medium- to large-sized insects, such as bees, [35] [89] other hornet and wasp species, beetles, hornworms, [90] and mantises. The latter are favored targets in late summer and fall. Large insects such as mantises are key protein sources to feed queen and drone larvae.
Palaeovespa florissantia, late Eocene. The Vespidae are a large (nearly 5000 species), diverse, cosmopolitan family of wasps, including nearly all the known eusocial wasps (such as Polistes fuscatus, Vespa orientalis, and Vespula germanica) and many solitary wasps. [1]
Hornets (insects in the genus Vespa) are the largest of the eusocial wasps, and are similar in appearance to yellowjackets, their close relatives. Some species can reach up to 5.5 cm (2.2 in) in length. They are distinguished from other vespine wasps by the relatively large top margin of the head. Worldwide, 22 species of Vespa are recognized.
There are roughly 300 species of solitary wasps in California, she added. Yellowjackets and paper wasps are the two most common social wasp species in Northern California, Kimsey said.
Large paper nest, upside down pear shaped, hanging from branches and eaves; also barns and attics. Some yellowjacket species nest in the ground. Very large paper nest in hollow trees, sheltered positions.
Sphex pensylvanicus is a large, black wasp, significantly larger than their congener Sphex ichneumoneus (the great golden digger wasp). [6] Males are smaller than females, at only 19–28 mm (0.7–1.1 in) long compared with typical female sizes of 25–34 mm (1.0–1.3 in). [2]
Megarhyssa macrurus, also known as the long-tailed giant ichneumonid wasp [1] or long-tailed giant ichneumon wasp, [2] is a species of large ichneumon wasp. [3] It is a parasitoid, notable for its extremely long ovipositor which it uses to deposit an egg into a tunnel in dead wood bored by its host, the larva of a similarly large species of horntail.
