Aphid eater hoverfly, Eupeodes sp., looking stunning on a rosemary flower just yesterday, November 4th. Pembroke college, Cambridge, UK.

As in most flies, the eyes seem bigger than the head itself, and often touch each other dorsally. Large eyes alongside tiny antennae is a great distinguishing feature to tell flies apart from wasps. Often, as is the case here, flies present a color pattern similar to that of a wasp: Batesian mimicry which offers protection against predation.

Amusingly, a cook passed by to collect a bunch for “formal hall”, that is, dinner.
