The Saxon Wasp (Dolichovespula saxonica) can occasionally be mistaken for yesterday’s wasp, the Norwegian, but doesn’t have norwegica’s red marks on the abdomen. (Although not ALL Norwegian wasps have this feature. It is another species which has colonised Britain in recent years (late 1980s), and as such has a south-eastern distribution.
Identifying this species can be tricky, but it is often more black than yellow, and the facial markings are quite variable.
It’s an aerial nesting species, building a hanging nest in bushes and trees, but also on man-made structures like buildings, bridges, benches, etc. Adults can be seen on bilberry and wild angelica.
