Great Black Digger Wasp

Fascinating facts about the Great Black Digger Wasp

• Female great black digger wasps immobilise each captured orthopteran with a trio of precise stings. The first sting is delivered to the neck and the next two to the thorax, a pattern that paralyses the prey without killing it. Because the paralysis is only temporary, the insect can remain alive for weeks while the wasp transports it to its underground nest. This method ensures a fresh food source for the developing larva awaiting inside the nest chamber.
• When a female wasp is carrying a paralyzed katydid or grasshopper back to her burrow, she becomes vulnerable to kleptoparasitism by opportunistic birds. Observations have recorded house sparrows and grey catbirds swooping in to snatch the prey from the wasp's grasp. These birds exploit the brief moments when the wasp is occupied with the heavy load, stealing the hard-won insects before they can be deposited in the nest.
• Each egg laid by the great black digger wasp measures only 5-6 mm in length and 1 mm in width, and the female secures it to the underside of the immobilised insect. The attachment is made between the prey's first and second pairs of legs, positioning the egg where the future larva can easily access the still-alive food source. After the egg hatches, the solitary larva consumes the same prey, which can support its growth for the ten-day larval stage.
• The great black digger wasp earned a place in scientific history when John Bartram's observations were read to the Royal Society in 1749, marking the first insect paper by a native-born New World author. The species was later given its formal Linnaean name in 1763, cementing its taxonomic standing.
• A sting from a great black digger wasp is described as painful, yet unlike many other wasps it does not cause the surrounding tissue to swell. This characteristic was noted by the 18th-century botanist John Bartram, who highlighted the sting's memorable pain without the typical inflammatory response.
