The growth is a rose-tack ringworm, and its cause is the insignificantly small weevil Diplolepis rosae. The female flies in late spring and lays her eggs in the newly opened rose leaf buds. It carefully lays its eggs in the root of a leaf, up to half a hundred eggs in one bud. When the larvae hatch after about a week, they burrow inside the leaf. With their hormone-like secretions, the larvae irritate the leaf so that it starts to grow abnormally: a hair-like tinge is formed on the outer surface, but around the larva is a soft and nutritious cell, which the larva eats. Each larva develops its own chamber around it. The larger the caterpillar, the more larvae it contains. The largest piles are ten centimeters long.
The weevil overwinters inside the acorn as a larva, cocoons at the dawn of spring and hatches after a couple of weeks. Almost all larvae develop into females, and the species therefore mostly reproduces virginally, without fertilization.
Takkuäkämä offers the caterpillar excellent protection from predators. However, the evil world invades the castle of the stingray caterpillar: in addition to its creator, several other insects also live in the tentacles. Some of them eat plant matter, some parasitize with stingray larvae.
How strange! I used google translate, but it could not translate your word. Do you know a english name for it?
