ladybuy eat coccid, aphids and whitefly.

The larva of the Lady Beetles (Ladybugs) eat a wide variety of other insect larva. The adult Lady Beetles mostly eat pollen.

That statement is only partly correct; adult ladybugs will eat pollen and nectar before going into hibernation, and may subsist on it at other times. Their much preferred (and needed) food sources are soft bodied insects and insect eggs.

triple, I've not heard that ladybugs are effective against thrips. They're (the thrips) are awfully mobile little things.

Cornell lists thrips as one of the known foods of Lady Beetles.
