In summer, large white butterflies fly in the gardens. On their wings there are no spots or strips, but veins appear through the pollen covering them. The name of this butterfly is hawthorn.

Hawthorn sits on flowers: here she feeds - sucks sweet juice

Hawthorn sits on flowers: here she feeds - sucks sweet juice. She sits down and on the leaves of the trees, on the grass - here she rests. Butterflies hawthorn sit on apples, pears, mountain ash: here the females are engaged in an important matter - the laying of eggs: a bunch of eggs, fifty or more pieces in each.

Tiny caterpillars are excreted from eggs. The sheet on which they live, becomes for them immediately and home and food.

Caterpillars of hawthorn produce a thin spider web, which they attach the edges of two adjacent leaves. The web is used to attach these leaves to the branch. Each caterpillar hawthorn produces a thin, barely perceptible spider web. But there are a lot of caterpillars, and dozens of cobwebs form a strong thread. This thread is firmly attached to the branch.

From cobwebs caterpillars weave wool and a blanket. They make it on the first day and only after that are taken for food. Their food is an apple tree leaf. For breakfast, for lunch, for dinner, all the same sheet. The leaf dries up, it becomes thinner, coagulates, but the blanket turns out to be thicker and warmer.

Maybe the hawthorn caterpillars know that winter will come? No, they do not know anything. Caterpillars just release silk threads and weave a blanket. This is their habit.

There are days, and caterpillars of hawthorn eat and weave... In August they stop eating. Two sheets, between which they lived, wrinkled, curled up. A package of two leaves was obtained, tightened with cobwebs and tightly tied to a branch. Inside the package, like a lining, was a blanket, and between it and the sheet lived caterpillars. Now, having ceased to eat, they are selected from under the blanket and are allowed to weave inside the package of the cradle: bags of spider webs. There are cocoons, and in each - on a tiny caterpillar hawthorn.

All autumn and winter there is a little house on the branch of the leaves, in which the hawthorn caterpillars sleep soundly. In spring, when buds swell, the caterpillars will wake up, crawl out of their cocoons.

Winter passed for them without food. The hungry caterpillars of the hawthorn begin to gnaw the kidneys, destroy dozens of future leaves.

In the beginning of summer caterpillars of hawthorn are immediately transformed into pupae in a tree. It takes two weeks, and white butterflies of hawthorn appear in the garden.

When the butterflies are small, they will not be immediately noticed. But if the caterpillars were many, then you will not miss the butterflies. And not only because hundreds and thousands of large white haws fly in the garden. There is another sign. Coming out of the chrysalis, the butterfly emits a drop of blood-red color. If there are many butterflies, then the tree looks as if sprinkled with blood. During the rain from such a tree, blood drops are dripped, bloody trickles will flow.

Hawthorn is a harmful butterfly. If in the spring there were a lot of her caterpillars in the garden, then there is no need to wait for a good harvest of apples.

What to do? How to protect trees? In autumn fall leaves, and "winter nests" will remain. They are immediately visible on the bare branches. The entire "stock" of hawthorn caterpillars is in these "nests". Remove them from trees and burn is not such a tricky business. There will be no "nests", will not be in the garden and caterpillars of the hawthorn.
