About 3 mm long. Could take pictures because many of them had drowned, in a small bowl of water next to a houseplant pot. I had thrown away a small amount of coffee grounds into this pot. These grounds had grown moldy. As far as I could see the larvae (white, almost transparant) were feeding on that, but they have disappeared by now. The plant (Peperomia obtusifolia) did not suffer. Could anybody tell if they are really fungus gnats, as I suppose? I'm writing articles about nature in a regional Dutch newspaper, could be an interesting subject. Thanks in advance!

Sciaridae are common in soil or stems of house plants. Some Drosophila are attracted to used coffee grounds. If you look closely, fungus gnat larvae have a solid black head while fruit fly larvae have only a thin black skeleton inside the head. |

Thanks for the reply. I've added an attachment to my post now (didn't succeed at first). |

The photo shows a female in family Sciaridae. Species identification usually requires a male under a microscope. |
