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, 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]
Once one cell is completed the wasp begins work on the next cell by excavating in a new direction off the main burrow. Most cells (approximately 5 – 12, but up to 24) are constructed 7 – 20 cm below grade with the egg, larva and pupal stages all developing within the confines of the single nest.
Yellowjackets and paper wasps are the two most common social wasp species in Northern California, Kimsey said. Social wasp colonies are started from scratch each spring by a queen who survives ...
Parasitoid wasps range from some of the smallest species of insects to wasps about an inch long. Most females have a long, sharp ovipositor at the tip of the abdomen, sometimes lacking venom glands, and almost never modified into a sting. [4] Parasitoids can be classified in a variety of ways.
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.
In light of the emergence of the "Murder Hornet" in North America, here's a reminder not to sleep on these less menacing (but still dangerous) bugs and rodents.
The stinger is a modified female organ called an ovipositor, which is unusually long and maneuverable in mutillids. In both sexes, a structure called a stridulitrum on the metasoma is used to produce a squeaking or chirping sound when alarmed. Both sexes of mutillids also bear hair-lined grooves on the side of the metasoma called felt
