Coleomegilla maculata Larvae (Pink Spotted Lady Beetle)

Most ladybugs you buy have one job and one flaw. They eat aphids, and then they leave. The dispersal flight is hardwired — they wake up after dormancy with one instinct, and it isn't loyalty. The larvae don't have that problem. They can't fly. They hatch, they walk, and they spend their entire larval life prowling the same plant you put them on, eating more or less constantly. By the time they grow up, they've already decided this is home. Coleomegilla maculata is North American and refreshingly un-fussy about its diet. It takes aphids, thrips larvae, whitefly, small soft-bodied pests, and a range of insect eggs — and, unusually for a lady beetle, it also eats pollen. That's the part worth caring about: a generalist that doesn't bail the moment pest pressure drops. When the aphids thin out, it stays fed instead of moving on, which is exactly the behavior you want from something you're counting on to stick around. It is not a spider mite solution. It'll take a mite if one wanders by, but if mites are your problem, that's a different aisle. Larvae are enthusiastic about food and indifferent about whose food it is, so crowd them and they'll start eating each other. Spread across the planting, they'll work it methodically.
