Wasps - the end is near


Almost at the end of the wasp season now. but there are still a few lethargic common wasps Vespula vulgaris in the garden, feeding on rotting fallen fruit. After cold nights they move very slowly, so it's easy to get close to them and get a good view of those powerful jaws. All season long they've been chewing wood to make paper for their nests, then catching other insects to feed their brood. Now, in their final days, they search for anything sweet to boost their flagging energy levels.



A few are feeding on the last of the late-season red-hot pokers Kniphofia sp. These popular garden flowers grow wild in South Africa, where they are pollinated by sunbirds that come to feed on the large volumes of nectar they secrete. The nectar trickles downwards in the dangling, tubular flowers and the wasps force their way in, so they often become covered in the sticky secretion and need to spend a lot of time cleaning their antennae afterwards.
