Bibionid flies mating

One from this summer: a pair of flies (family Bibionidae) spotted mating in my garden. Quite a spectacular degree of sexual dimorphism - the female is the large colourful one with the small head, compared with the skinny male with the big head/eyes. Females can be quite conspicuous in the warmer months, flying slowly around lawns (the larvae feed on grass roots among other things). Posted by Picasa

You're not putting them up fast enough! This is terrific.
