Why does your Anoectochilus roxburghii have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The tiny black flies are likely fungus gnat adults, which lay eggs in moist organic matter. Their larvae feed on the delicate root systems of Anoectochilus roxburghii, potentially causing root decay and nutrient deficiency.
Jewel Orchids require high humidity but hate soggy substrate; constant wetness promotes the growth of fungi and algae that serve as a primary food source for fungus gnat larvae.
Old, decaying sphagnum moss or bark in the orchid pot provides the perfect breeding ground and nutrient source for small dipteran flies.
