Identifying it in Mississippi

Technically a large yellowjacket, black with an ivory-white face, and the most defensive of the group. Multiple stings during a single encounter are typical because the colony responds together and follows for a distance.

Locally, the species most often confused with it are carpenter ant bite, honey bee sting, fire ant sting — all of which are also recorded in Mississippi.

Season in Mississippi specifically

Records in Mississippi concentrate in April, August, September, October, which is what local sighting data shows rather than a national average — seasonality shifts substantially with latitude. The general bite season in Mississippi runs March to November.

Because enclosed grey paper nests the size of a football, hanging in trees, on sheds and under eaves, exposure in Mississippi tends to be concentrated in specific places rather than spread evenly — which is why a bite history ("where were you in the 24 hours before?") narrows the answer faster than the appearance of the mark.

Care

  1. leave the area quickly — this species pursues
  2. cold pack, antihistamine, pain relief
  3. adrenaline auto-injector if prescribed
