Death's head?

Made an early and brief visit to the allotment, getting a string of messages while I was there that ended with the triumphant news that Iain had managed to get the pump working, so they have a water supply. Phew. Otherwise they'd have had to go back to commuting till it was fixed, which wouldn't have been popular with anyone.

Came back down the Kirkgate and noticed a new piece of street art - seems to be a death's-head hawkmoth. Are those bombs it's carrying on its rear wings?
