Okay, spiders are arachnids, not insects, but since we don't have a general 'arthropods' category I thought I'd stick these in here.
Been seeing a lot of cross orbweavers lately (also called diadem spiders or European garden spiders). The first two images show a little lady that's a little over 2" (5 cm) with legs.
One of the interesting things about cross orbweavers is that they have a tendency to run and hide when their webs are disturbed. The third image shows one doing just that, hiding on a rosebush. And no, I wouldn't have seen her if I hadn't seen her move. The last one is a panel showing her unwinding herself after deciding the coast was clear.
