Saw this large yellow and black winged insect on my roof terrace in Malta today. I photographed it next to a 10p coin for scale. I'd really like to know what it is so if anyone can help I'd really appreciate it.
This is a Scoliid wasp, perhaps mammoth wasp - Megascolia maculata.
(Scolia hirta is similar but the yellow forms two bands not four spots.)
If I may quote:
"Females have a yellow face and short antennae, while the smaller males have a black face and longer antennae.Both are marked with yellow bands on their abdomens, which may be broken and show as four yellow spots"
