What are the appearance and life characteristics of the pea elephant in Insects .

Insects》The appearance and life characteristics of the pea elephant are as follows:

1. The shape of the pea elephant.

Small-headed, large-mouthed, dressed in gray clothes with brown spots, with flattened elytra and two large black moles at the base of the tail.

Short and stout, that's what a pea elephant looks like.

2. Characteristics of life.

1 generation a year, adults overwinter in the crevices of storage rooms, field relics, bark cracks, loose soil and packaging. The following spring, they fly to the spring pea fields to feed, mate, and lay eggs. Adults need to feed on pea nectar, pollen, petals or leaves for 6-14 days to supplement nutrition before they begin to mate and lay eggs.

The eggs are generally scattered on both sides of the pea, mostly on the bean in the middle of the plant, each female can lay 700-1000 eggs, and the peak spawning period is generally in mid to late May. The egg stage is 7-9 days. After hatching, the larvae are bored into the bean ing, and the larval stage is about 37 days, and it pupates in the bean grain when it is mature.

The peak pupation period is in early to mid-July, and the pupal period is 8-9 days (this period is stored with the harvested peas).

Brief introduction. Now it has spread all over the world except Australia. In the 50s of the 20th century, it began to harm in China, and in 1957, Hebei Province investigated, except for Zhangjiakou, the whole province has occurred. In 1965, it was introduced to Tacheng and Yili areas of Xinjiang.

Although the quarantine personnel discovered it in time, no one caught it, resulting in a rapid spread.

In the autumn of 1958, when a large number of disaster relief seeds were transferred, broad bean elephants and pea elephants spread from Hunan, Hubei and other places to central and southern Guangxi, resulting in the Guilin area.

It became a serious occurrence area for these two species. Since the 90s, the central region of Gansu.

Occurs severely. Transmission is mainly carried out through the transport of damaged seeds. Harmful to peas, kidney beans, and wild peas.

Cassia, gorse, mucuna pruriens and other plants.

1.The pea elephant is oblong in shape, black, with a body length of 4.5 mm and a width of 6.8 mm.

2.The antennae are 4 segments at the base, and the anterior and midfoot tibiae and tarsal joints are brown or light brown.

3.The head is pointed, and the back is light brown hair.

4.The dorsal plate of the prothorax is broad, densely notched, with black and grayish-white hairs on the back, triangular hairy spots in the middle lobe of the posterior margin, narrow at the anterior end, and 1 posterior finger in the middle of each side of the fangs.

5.The small scutellum is nearly square, the posterior margin concave, covered with white hairs.

6.Elytra with 10 longitudinal stripes, covered with brown hairs, mixed with white hairs along the base, and 1 oblique stripe composed of white hairs later in the middle to the outer margin.

7.Habits: 1 generation a year, adults overwinter in the cracks of storage rooms, field remains, cracks in bark, loose soil and packaging.

8.The following spring, they fly to the spring pea fields to feed, mate, and lay eggs.

9.Adults need to feed on pea nectar, pollen, petals or leaves for 6-14 days to supplement nutrition before they begin to mate and lay eggs.

10.The eggs are generally scattered on both sides of the pea pod, mostly on the bean in the middle of the plant, each female can lay 7,001,000 eggs, and the peak spawning period is generally in mid to late May.

11.The egg stage is 7-9 days.

It mainly writes about the pea elephant's help to humans, highlighting the pea elephant's ability to meet the characteristics of humans. "Insect Story", also known as "Insect World", "Insect Story", "Entomological Notes" or "The Story of Insects", is a long popular science literature written by French entomologist and writer Jean Henri Casimir Fabre, with a total of ten volumes.

This work is a masterpiece of entomology that summarizes the species, characteristics, habits, and marriage habits of insects.

Souvenirs Entomologiques (also known as "The World of Insects", "Insect Story", "Entomological Notes") is a long biological work written by French entomologist and writer Jean-Henri Casimir Fabre, a long work of biology in ten volumes. The first volume was published in 1879 and the whole book was published for the first time in 1907.

This work is an insect biology work that summarizes the species, characteristics, habits, and marriage habits of insects. The author integrates the colorful life of insects with life perceptions, and reveals his respect and love for life between the lines.

Insects "Pea Elephant."

Main content: It is the largest butterfly in Europe and wears a maroon velvet tunic with a white fur tie. The wings are full of gray and white spots, a pale white zigzag line passes through it, the periphery of the line is smoky gray, the wings ** have a round spot, like a big black eye, and the pupils are flashing black, white, maroon, and cockscomb.

The red one is a rainbow of unpredictable colors.
