Parischnogaster striatula is a species of social hover wasps found in Southeast Asia.
P. striatula is also different than typical wasps because the queens are not the only ones who possess reproductive capabilities; other females also have developed ovaries.
While the Stenogastrinae taxonomy and phylogeny are still under study, it is known that Parischnogaster species are split into two subcategories, with P. striatula being closely related to P.
P. striatula is a commonly found species in Southeast Asia, specifically the Indo-Malaysian area.
Their unique nests are found in areas sheltered from rain, including along forest roads or trails, under the vaults of caves, and human buildings such as a gazebo.
[1] Social interactions are more frequent during the middle of the day, between off-nest activity peaks, when many females return to the nest.
Newly emerged females will most likely become workers by helping out with the nest before leaving to find or acquire their own colony.
[1] When laying eggs, P. striatula secretes a sticky abdominal substance, created by its Dufour’s gland, and collects it in her mouth.
Then as the eggs emerge from her abdomen, she uses this abdominal substance to handle them and proceeds to stick them into an empty cell.
The nest can be smooth to match buildings, or rough to watch the surrounding woods and trees.
They gather various materials to garnish the exterior of the nest with decorations to give it a rough texture.
[1] P. striatula distinguishes between an alien or nestmate approaching their nest by the incoming flight pattern.
[4] Although P. striatula colonies are small, they still live in close quarters which can lead to the a rapid spread of disease throughout the nest.
