Cicada killers are large, solitary wasps in the family Crabronidae. The name Johanna refers to my wife.". Until now, everything that scientists knew about the group of insects in the Afrotropical region was based on just 30 specimens. "Extending the research to the African continent is important, because our goal is to understand the global diversity of the parasitoid insects which are extremely species rich. In addition to describing two new parasitic wasp species, Epirhyssa johanna and E. quagga, scientists collected dozens of specimens belonging to ten previously described species. Asian giant hornets from Japan and East Asia already have established themselves as invasive species in other nations, such as South Korea. Now, at one single Ugandan site, we found large numbers of both females and males. Bees, Ants, Wasps and Similar Insects of Virginia Showcase listing of Bees, Ants, Wasps and Similar Insects found in the state of Virginia. The name may be applied to any species of crabronid which preys on cicadas, though in North America it is typically applied to a single species, S. speciosus.

But the latest research suggests that designation was based on poor sampling -- not an actual lack of species. Until now, some scientists characterized tropical rhyssines as species-poor. Oct. 9 (UPI) -- Finnish researchers conducting field studies in Africa have discovered two new species of giant parasitic wasps. Parents' 'memory' of environmental stress inherited across generations, Pesticides affect bumblebee genes; scientists call for stricter regulations, Biologists discover 11 new rain frog species in the Andes, Unique glowing click beetle found in southwest China, Common Costa Rican frog species consists of several 'cryptic' species. This species occurs in the eastern and midwest U.S. and … The discovery, described this week in the journal ZooKeys, suggests the group of insects known as Afrotropical rhyssine wasps is more diverse than previously thought. However, since there are multiple species of related wasps, it is more appropriate to call it the eastern cicada killer. During their survey in Uganda's Kibale National Park, researchers collected 456 rhyssine wasp specimens. Hopkins and company previously surveyed tropical rhyssine diversity in South America.

The Asian giant hornet, Vespa mandarinia, is the world's largest hornet species. "The other species became Epirhyssa johanna. "In our Amazonian research, we have described ten large-sized South-American species new to science and our understanding of the diversity of South American tropical rainforest parasitoid wasps has changed," said Turku researcher Ilari Sääksjärvi. The Asian giant hornet can be found in the Primorsky Krai, Khabarovsky Krai (southern part only) and Jewish AO regions of Russia, Korea (where it is called 장수말벌 "general officer hornet"), China, Taiwan (simplified Chinese: 大虎头蜂; traditional Chinese: 大虎頭蜂; lit.
