The report on the www.agric.wa.gov.au website says that there can be confusion in identifying the different wasps as they both have black and yellow stripes. Marc Widmer, senior technical officer for the Department of Agriculture and Food, is one of the authors of the Wasp identification guide.
The guide has lists of features that can help identify the differences between the two wasps. European wasps are short and stout, similar to a bee, while paper wasps are thinner and longer.
Perhaps the most significant and visible difference between the two wasp families is their antennae. The guide explains how European wasps feature completely black antennae, whereas paper wasps possess antennae that are orange-brown in colour.
Another major difference between the wasps is their nesting habits. Paper wasp nests can be found above ground, while European wasp nests will be hidden below ground. The Department website reports that many have already been found this summer.
“So far this summer 17 nests have been found - one in Kalgoorlie and 16 in metropolitan Perth, including one in Bassendean, one in Osborne Park and 14 in the Kewdale and Welshpool areas.”
Mr Widmer made clear that identifying and reporting suspicious wasp activity was important for community safety. He also said that reports from the public are “critical” in finding the nests and enabling pest control experts to destroy them.
