The description of the insect as well as the lack of a sting on
the site suggested a wasp (Vespula) as the culprit. However,
we were puzzled by the fact that in this patient another previous
Vespula bite during the SIT course had not caused any
systemic reactions. By thorough interview we found that in
that rural area, characterized by many pastures, the culprit
insect was rather common. Moreover, the patient reported
that the insects flew around him for some time before biting
him. Also the blood dripping on the site of the bite resembled
more a tabanus bite
