What is eating my yellow-white maxillaria?
Yellow-White Maxillaria (Maxillaria luteoalba) grows as a clumping epiphyte where mealybugs readily hide in the overlapping sheaths of its pseudobulbs, making them the primary pest concern. Spider mites attack in dry heated rooms. Scale can also colonize stem bases. Monthly inspections and prompt alcohol spot-treatment followed by neem oil sprays keep infestations in check.
