What's eating my masdevallia coccinea?

Masdevallia coccinea, a vivid cool-growing Colombian orchid, is most vulnerable to spider mites, which thrive when temperatures rise and humidity drops. Fungus gnats attack fine roots in wet media, and mealybugs shelter in leaf sheaths. Cool, humid, and well-ventilated conditions replicate its cloud-forest habitat and naturally suppress pest pressure.

Silvery stippling and webbing on leaves; severe infestations cause leaf drop and death in warm rooms Boost humidity above 70%; move to a cooler spot; treat with insecticidal soap or neem oil weekly

Root tips chewed by larvae; leaves yellow and growth stalls despite correct watering Use yellow sticky traps for adults; drench media with Bti solution; improve drainage and reduce watering frequency

Cottony clusters in leaf sheaths and at the crown; sticky honeydew and stunted new leaves Apply 70% isopropyl alcohol with a cotton swab; systemic imidacloprid drench as a last resort
