General Species Information:
Found in the Adelaide Hills and possibly elsewhere
There are two very similar introduced wasps in South Australia. This one & the much less common English Wasp (Vespula vulgaris). You probably couldn't tell the difference between them with the naked eye. But with photo's the difference becomes evident. This one has a solid yellow band behind the eye; V. vulgaris has a black patch in the band behind the eye. This one has a thin vertical black line on the face with a black dot either side in the yellow; V. vulgaris has a fat vertical black line on the face with no dots.
The queen looks the same as the worker, with the only reliable differentiation being size. The queen ~20mm long; while the worker is ~14mm long.
The big surprise for us after photographing one was realising how hairy they are. The look very smooth and hairless with the naked eye.
They are one of the most aggressive wasps in Australia; attacking just because you are too close to YOUR picnic lunch. Probably second only to the European Honeybee.
Thank you to Dave Holland for pointing out that males have long antenna and 7 terga of abdomen rather than 6; and are stingless.
