The Transformation of the Gall Bee and the Oak
There are trees in the world, and their name is oak. Wild forests in the mountains can be seen everywhere. There are two bees, one is the tubercle gall wasp, and the other is the horned gall wasp, which often gather on the oak tree. For the strange changes of the oak tree, they create various abnormalities.

The tubercle gall wasp is small in shape, brown in color and hidden in the leaves. The female uses the needle-like oviparous tube at the end of the abdomen to pierce the young branches and young leaves of the oak tree. The egg enters with the needle and lives in the tree. When the egg enters, the tree senses the foreign body, and then changes to resist it. The cells of the tree are stimulated, proliferating and swelling, and gradually This gall varies in size, like a tubercle, with rough epidermis, or yellow or brown. The larvae of the tubercle gall feed themselves with the nutrients in the gall. When they grow up, they break the gall and emerge, turn into a bee, and soar through the forest.

Horned gall wasp, also a frequent visitor to the oak tree. Its egg-laying method is the same as that of the tubercle gall wasp, but where it is laid, the egg causes different changes in the tree body. Horned gall wasp eggs go to the leaves or branches of the oak tree, giving birth to horned galls. This gall is shaped like a beast horn, sharp and hard, and the epidermis is dark. Horned gall wasp larvae dormant in it, protected from foreign enemies by horned galls. When the time is ripe, the larvae metamorphose, break free from the bondage of the horned gall, and return to nature.

Because of the horned gall wasp and the horned gall wasp, the branches and leaves of the oak tree are covered with the horned gall and the horned gall, with a peculiar shape, which is very different from the ordinary oak tree. However, although the two changed the appearance of the oak tree, they also added a unique scenery to the mountain forest. In the mountain forest, all creatures depend on each other. The horned gall wasp and the horned gall wasp reproduce in the oak tree. Due to the influence of the two, the oak tree presents a different style and forms a wonderful picture of nature together.
