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.
Megarhyssa atrata, also known as the black giant ichneumonid wasp, is a species of large ichneumon wasp. It is known from North America, [1] where it is found from Quebec, Michigan, Ohio and North and South Carolina to Florida. [2] Adults are on wing from May to July. [citation needed]
Megarhyssa, also known as giant ichneumonid wasps, giant ichneumons, or stump stabbers, [1] is a genus of large ichneumon wasps, with some species known for having the longest ovipositors of any insects. They are idiobiont endoparasitoids of the larvae of wood-boring horntail wasps. The ovipositor can be mistaken for a large stinger. [2]
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.
Megarhyssa nortoni is a predatory insect. Its larvae are parasitoids of horntail wasp larvae in coniferous trees. The adult female hunts horntail larvae for egg placement. It smells wood-eating fungus, utilized by the horntail larvae to predigest wood pulp, and uses its antennae to detect vibrations made by the horntail larvae.
Rhyssa persuasoria, also known as the sabre wasp, is a species belonging to the family Ichneumonidae subfamily Rhyssinae. Members of this subfamily, including those of Rhyssa and the allied Megarhyssa , are also known collectively as giant ichneumonid wasps or giant ichneumons.
Wasps of the genus Sphex (commonly known as digger wasps) are cosmopolitan predators that sting and paralyze prey insects. Sphex is one of many genera in the old digger wasp family Sphecidae , though most apart from the Sphecinae have now been moved to the family Crabronidae. [1] There are over 130 known Sphex species.
