Recently i detect many small black parasite wasps (not talking about Fungus Gnats) They are flying smoothly and searching the surface of the soil (around the indoor pots).
I don't know if they are helpful or harmful ?
Also I want to know name of this insects.
plants are vary by many types(mimosa plant, Stapelia gigantea, ricrac cactus, red and yellow Millet, Parsley), i know the wasp's comes from a Stapelia gigantea and then proliferated in this 3 months (about 10 wasps). about the used soild: i used a vermicompost, i bought it vacuumed and bagged firmly! the only pet i scouted inside the soil, is Fungus Gnat
attached some pictures of them and pots
they are small as 0.5mm x 2mm and always exploring the surface and inside of the soil holes.
