The front of butterfly wings is blue-purple with metallic luster, and the buttock angle of the rear wing has orange spots, with a long and short tail process at the end, and the tail end turns white. The reverse side of the wings is light yellow, with obvious reddish-brown stripes, and the center of the stripes is silver line. When resting, the back of the wing stands, and the black and red spots on the hip angle of the hind wing are very similar to a head. The four tail processes are swinging leisurely, looking like the head of a butterfly, and the "tentacles" are shaking, while the real head and tentacles are motionless. At this time, if an enemy attacks, the fake head attracts its attention. The gray butterfly took the opportunity to escape before the butterfly could clear the field. Even if the enemy pounced on the false head, only part of the rear wing was damaged, and the gray butterfly was able to escape.
Monarch butterfly
Monarch butterfly is a large black and orange insect, and also an excellent animal traveler with amazing flying ability. In North America, they fly back and forth more than 3,000 kilometers every year between their winter homes in Mexico and distant breeding grounds in the south. In late summer, monarch butterflies return to the south to escape the cold winter. They often curl up in the same tree for the winter. Monarch butterflies can absorb toxins from milkweed and other plants they eat and store them in their bodies in order to compete for shelter and sun exposure. Their bright colors can often serve as a warning to the enemy. When their bright colors don't work and it's hard to scare the birds away, they will choose to die with the enemy. Therefore, for those birds who are indifferent to bright warning colors, they are a very dangerous animal.
White butterfly with cabbage
Pieris rapae may not be the most beautiful butterfly in the world, but it is one of the most tenacious and numerous butterflies. Their larvae feed on cabbage and similar plants, so they become pests of these crops. Pieris rapae originated in Europe. Because of their rapid reproduction and tenacious vitality, their numbers have greatly increased. Today, this butterfly can be seen on all continents except Antarctica.
butterfly
Dead-leaf butterfly, as its name implies, is a butterfly that can become like a dead leaf, but this does not mean that its whole body color is dim. In fact, the back of its wings is very bright and looks beautiful when flapping in the air. When resting on a branch, the butterfly's two wings are put together, and the ventral surface of the wings faces outward, showing the appearance of dead leaves, because the color of the ventral surface of the wings is almost the same as that of dead leaves. The unique way of stopping leaves makes it difficult to be found by enemies in the tree. This kind of appearance, shape or stain formed in the long-term evolution process is similar to other biological or abiotic abnormalities, which is biologically called "mimicry". The most amazing thing about the dead-leaf butterfly is that the pattern on the ventral side of its wings can imitate the vein structure and pattern of the leaves on the tree where it lives, and its color is no different from that of dead leaves, and the edge of its wings is serrated like dead leaves. The degree of imitation has reached a superb level!
