inanis

Yes, the spots on tergite 2 (the first full abdominal section visible after the thorax) are yellow, not orangey-chestnut. Also, the thorax has a pale oblong above the yellow scutellum. The extra band is not important. The best way to tell is to look beneath...inanis has a yellow sternite 2, zonaria black.

inanis is also smaller, but not all zonaria are really huge.

V inanis

Yes well spotted Chris there are also some minor differences to the legs but as said above is the most reliable indicator esp in the field V zonaria presents mainly in the South

inanis vs zonaria

The underside differences are reliable, but there is also a reliable difference in shape of the topside abdominal markings (rather than colour, which can very), see discussion here:

Both species are spreading from the south and are now widespread in the midlands and beyond.
