General Species Information:
Found in the Adelaide Hills and possibly elsewhere
These are known to be aggressive, but only if you disturb their nest. Unfortunately gardeners often don't realise a nest is in the hedge they are trimming until they are attacked.
These are social wasps, so build their nests communally. But unlike nesting bees & ants which have queens, these are all fertile females populating each cell with their own egg. They've found a benefit in nesting together and protecting the nest as a group.
Jonathan Hoskins said "The two subspecies do divide fairly decently by location (ssp. humilis is the more southern range, ssp. synoecus is more northern and the only one introduced to Western Australia). In terms of appearance, ssp. humilis is darker with fewer yellow markings on the abdomen and no yellow lines on the propodeum (the rear portion of the thorax). Ssp. synoecus is more yellow with more extensive yellow on the thorax and paired yellow lines on the propodeum."
