The first one found in Oz of the European Wasp (common wasp i think you call them) was about the size of a Mini (olde style). The entrance hole was the size of a basketball, and it was at the edge of a sports field in an area that was very rarely mowed or slashed. Just really overgrown long grass. No reason for anyone to go there. As there is not a serious winter in Oz, the wasps didn't die off each year, so the colony got bigger and bigger. Until the local authority bloke was ordered to slash the area on a tractor and thats when we found we had European Wasps in Australia. He was badly stung, but survived.
Our own native wasps and hornets are big and pretty mean, but they don't live in very big colonies and are hard to rile. Hurts when they sting though. They cant compete with the European Wasps as far as breeding rate.
