Gall Fly

Description:

Sorry about the out-of-focus pics, but this fly was not the main target, it walked in the frame while I was zeroing on a butterfly... This is a medium sized fruit fly, roughly the size of housefly, with grey body with yellowish stripes; and transparent mottled wings.

Habitat:

Mediterranean garden in urban setting, coastal Croatia.

Notes:

Seen feeding on rotting fruit of one of older varieties of Cherry-plum, (Prunus cerasifera). Unfortunately, the fruit of this tree is not very appreciated, except for making some low-quality booze... The tree in this story belongs to our neighbour, who never harvest it nor use the fruit; so the floor of the entrance to our garden and the adjacent alley are always completely covered by rotting and fermenting fruit (yep! that corner of the garden always smells of spilt booze...) attracting loads of unwanted visitors - wasps, flies, chaffers, rats... Of course, there are some birds and butterflies as well. This year I experimented with some of the remaining fruit; and managed to produce a home-made fruit sirop, jelly and jam; so the next year we may solve the problem...
