Lindorus lophanthae
Scale Who?
Some predators pick and choose. Lindorus doesn’t. These scale-specific lady beetles feed on all life stages — eggs, crawlers, and even adult armored scale tucked under their waxy shells. They’re small, stealthy, and extremely good at what they do.
Whether you're up against California red scale, black scale, oleander scale, or a dozen others, Lindorus lophanthae doesn’t flinch. They're one of the few predators that reliably attack hard scale, soft scale, and mealybugs. If it’s sucking plant juices and hiding behind a shell, it’s fair game.
