A new identification key highlights 74 species of cuckoo wasps -- wasps known for their propensity to steal other insects' nests, as cuckoo birds do with other birds -- found in the Nordic and Baltic countries. This includes the "Northern" cuckoo wasp (Chrysis borealis), which is new to science.
Some insect larvae can twitch and whip inside their cocoons in order to "jump" to shadier, or more favorable, environments. Researchers say this is a unique survival technique only seen in select wasp species.
Some parasitic wasp species lay their eggs in the bellies of wolf spiders so that the larva can feed of the vertebrates' blood. While this does not harm the spiders initially, when the larva mature they end up killing their hosts. The recent findings highlight the diverse parasitic relationships among animals.
Five new long-haired parasitic wasp species have been found in India. A recent study revealed these insects prefer spider eggs as their host of choice. The uniqueness of these insects suggest there are many more parasitic wasps to be found.
In a huge genus of wasps that is still mostly unknown to scientists, five new species of "long hair" wasps that parasitize spider eggs have been declared in the Indian subcontinent.
Aa currently evolve into two genetically distinct species as a result of apple trees changing their fruiting cycles, they're have a domino effect on predatory wasps, a process known as sequential speciation.
A new wasp species belonging to the Spasskia genus has been identified in China, expanding on the number of disturbingly parasitic wasps that can be found around the globe.
