Neither frogs nor lizards eat ladybugs, even spiders, and they refuse caustic insects. Even the Central Asian poisonous spider - the tarantula refuses such food, the ladybug is too tough for him. When she eats to penetrate the spider's mink, he drives her out, pushing the bright insect with the blows of her forepaws.Children simply adore these colorful insects. they like to play with them in summer and spring.
The whole secret of the peculiarities of ladybugs is the poison cantharidin, it is contained in an orange drop of caustic liquid.

When tightening the legs, a caustic drop immediately appears. This poison, contained in a liquid, unpleasantly burns the pharynx of birds and other animals. The yellow liquid produces an unpleasant odor, and this is not to everyone's taste. Poisonous cantharidin serves as a reliable protection against predators. Some beetles are even masked by its color, hoping that the birds will not touch them.
