Introducing ‘The Bone-house Wasp”:

Introducing ‘The Bone-house Wasp” Kingdom: Animalia Phylum: Arthropoda Class: Insecta Order: Hymenoptera Family: Pompilidae Genus: Deuteragenia Species: D. Ossarium Common Name : ‘The Bone-house Wasp’ (1) Figure 1. Female ‘Bone-house Wasp’ (1)

The Discovery of D. ossarium:

The Discovery of D. ossarium This new species of wasp was discovered during an ecological survey of the Gutianshan Natural Nature Reserve in South-East China (Sept. 2011-Oct. 2012) (2) Artificial, above-ground, nesting sites were set up by researchers from the University of Freidburg (Germany) to trap and evaluate the local cavity-nesting wasps (2) During the survey, an undefined pompilidae wasp’s nest revealed a unique nest-protection strategy that had never before been seen in the animal kingdom (2) Figure 2. A ‘spider-hunting’ Pompilidae wasp. (3)

A Unique Nesting Strategy Revealed:

A Unique Nesting Strategy Revealed Deuteragenia ossarium , like many other insects, builds a nest with a row of brood cells to house her developing wasp larvae (2) Each brood cell features one paralyzed spider, a single egg, and then is capped off by a dirt plug. A nest can have anywhere from 1 to 6 brood cells (2) The last cell, or closure cell, is known as the vestibular cell, and traditionally is empty (2) Figure 3. The typical nesting cavity of D. Ossarium and developing pupae. (2 )

What Makes this New Species Unique? A Vestibular Cell Filled with Dead Ants:

What Makes this New Species Unique? A Vestibular Cell Filled with Dead Ants D. ossarium was found to be filling her vestibular cell with dead ants, the majority being an aggressive local ant species (up to 13 total ants) (2) This nest-protecting strategy had never been seen in the animal world prior to this discovery (2 ) The ant filled vestibular cell acts as a deterrent chemical messenger to parasitic predators During the study, D. o ssarium’s nest dwellings were parasitized only 3% of the time compared to 16.5% for all other species combined (2) It is believed that the parasitism events of D. ossarium’s nest occurred prior to her ant-filled vestibular cell being built (2) Fig. 4. Vestibular cell filled with Dead Ants. (2)
