Ant

Ants can live wherever they have living conditions and are the most polymorphic social insects in the world. It is estimated that only about half of all ant species exist - currently about 11,700 species. A larger study of the ant fauna remains to be conducted. There are more than 600 identified ant species in China. Ants belong to the phylum Arthropoda, class Insecta, order Hymenoptera, and family Formicidae. The creature with the strongest ability to fight against natural disasters.

Earthworms are common terrestrial annelid animals that live in the soil and come out at night. They feed on livestock and poultry manure and organic waste, swallowing it together with the soil. They also eat plant stems and leaves and other debris. Earthworms can loosen the soil, improve the soil, improve fertility, and promote agricultural production. There are about 2,500 kinds of earthworms in the world, and 229 species have been recorded in my country. The genus Pheretima has a wide range of species.

gecko

They are distributed in warm areas, jungles, and deserts, and can even be found in tropical and subtropical countries around the world in places with small canopy holes. However, because geckos are seasonal animals, the temperature is above 10 degrees Celsius. If you are still active in an environment of 11 degrees Celsius or below, you will die. Therefore, geckos that generally live in subtropical areas will hide and hibernate every winter. Therefore, geckos are relatively rare in cold areas such as temperate and frigid zones. Most geckos (about 75%) are crepuscular or nocturnal.

How to differentiate between butterflies and moths?

Appearance

Moths are the general name for insects of the order Lepidoptera. It is a complete metamorphosis insect. The adult antennae are whip-shaped, filament-shaped, feather-shaped, spindle-shaped, etc., and vary from species to species. It has one eye and a broad abdomen.

Butterflies are generally brightly colored, with various patterns on their wings and body, and a pair of club-shaped or hammer-shaped antennae on their heads. The largest butterfly has a wingspan of 24 cm, while the smallest only has a wingspan of 1.6 cm. Some are poisonous.

living habits

The main difference between moths and butterflies is that moths are mostly active at night, with their wings covering their bodies like a roof when stationary, their bodies are mostly dark, and their antennae are feathery, tooth-like or filamentous; butterflies are mostly active during the day and are stationary. The wings stand upright on the back, the body is bright, and the antennae are hammer-shaped or rod-shaped.
