This Super-Stinger Wasp Was Just Discovered in the Amazon
Deserved or not, the Amazon has developed a reputation for hosting animals, insects, and other creatures that appear to exist solely to terrify humans. And everywhere in the world, you’ll find parasitic organisms that thrive when they siphon blood or other resources from hosts.
A new entrant has emerged in both of these charts: Calistoga crassicaudata, a wasp recently discovered in the Amazon that sports a stinger roughly half the length of its 9.8-millimeter-long body. The insect may as well come out of the workshop of Alien designer H.R. Giger: Its methodology is to impale prey with the stinger, paralyzing it, and then depositing eggs inside so they can hatch later. The hatching usually causes the host—typically a spider—to burst open and die in agony as C. crassicaudata laughs maniacally. Metaphorically speaking.
Researchers from the University of Turku, Finland, made the discovery between the Andes and the Amazonian lowland rainforest and reported it in the journal Zootaxa. The new species appears to be amazing wasp experts by the sheer magnitude of its built-in spear, also called an ovipositor, that delivers both venom and the female's eggs.
"I have studied tropical parasitoid wasps for a long time, but I have never seen anything like it," entomologist and co-author Ilari E. Sääksjärvi said in a statement. "It looks like a fierce weapon."
The good news? It’s not really strong enough to pierce human skin, so should you find yourself in its vicinity, you probably don't need to worry. Instead, worry more about the common paper wasp, which has a barbed stinger, takes only 0.5 seconds to impale you, and can retain its stinger to continue its assault.
