Very small fly, less than 2mm body length, drifting slowly in the house. I would say it is a Mycetophilidae: Sciara thomae?

Hi Joaquim,

no doubt - a member of the so called black fungus gnats (Diptera: Sciaridae). But for Sciara thomae it is unlikely. Most probable Bradysia difformis or Bradysia ocellaris which are common indoors.

Thank you, xylo! That was a tough one for me.

I guess these are the small sciarids that develop in the soil of indoor plants. They seem to be quite common. It is nice to find out what they are. Which other sciarid midges do occur in such a habitat.

Actually I just made photos of the same or very similar species the other day.

Well, common indoor findings beside the two mentioned species above are: Lycoriella ingenua, Lycoriella castanescens and Pnyxia scabiei. But identification only on photos are not possible with certainty.

so long,
