The killer wasps are a part of the Sphecius speciosus and between 40mm and 50mm long with females being larger than males and both being a black and brown colour, with yellow markings around the abdomen and the head, with the wings being an amber colour. The killer wasps begin to appear as adults around June and July and can be seen in and around flowers or digging there burrows in soil or sand. Female killer wasps prefer to dig their burrows in sand that is dry, bare, very god drainage and has plenty of surface exposed to the sunlight. Killer wasps capture cicadas by stinging them resulting in paralyzing the cicada. The killer wasps then puts the cicada in the burrow with an egg laid on it and seals it in to stop anything getting to it. Killer wasps only produce a generation per year with the eggs having been laid, they spending that winter in the burrow till the following year. Female killer wasps live for around 30 days and are less likely to be seen after September. Damage caused by killer wasps are tiny mountains of dirt from them building nests. These will normally disappear with the first rain washing them flat.
