Macrocheles robustulus

Macrocheles robustulus is slightly larger than the well-known Hypoaspis (Stratiolaelaps scimitus). Its effect in the soil is similar; It is often used against fungus gnats, potworm (lyprauta) and thrips pupae, but also eats nematodes and eggs of various species such as duponchelia, cabbage flies, moss mites and root mealybugs.

Because macrocheles has a preference for eggs, it is also ideal for controlling flies in stables and manure piles. It is often released in combination with parasitic wasps such as Muscidifurax raptorellus.
