Uniform reply: Not drawn. That's it.
@Museum Magazine Supplement:
The two red dots are the compound eyes of the nymphs inside, and the "mouth" is the egg breaker in the forehead, which is used to top the broken eggs. These pictures are not the same kind of bug because the shape of the egg breaker is different. Eggs that are quick to hatch will show these characteristics
ent: "It is only when an egg that is about to hatch will show these characteristics", meaning that it will immediately go through such a process...
Palomena prasina (red-tailed bug, common in Europe). The eggs look like this:
(Well, it's actually like this)
But after growing up, it was like this...
(The above three pictures are from andy newman)
(Yes, the last one is doing what you think they're doing)
Odorous glandular pores, which can secrete odorous liquid, volatilize into odorous gas in the air,
In fact, nymphs are also quite cute
Bug family
The family Pterophoridae pentatomidae; Stinkbug Hemiptera 1 family. Formerly known as bugs. Such insects have stinky glandular holes, which can secrete odorous liquid and volatilize into odorous gas in the air, so there are common names such as fart worms, bed bugs, and stinky big sisters. About 500 species are known in China.
The host is mainly harmful to rice, but also wheat, millet, corn, sugarcane, beans, potatoes, citrus and so on.
For the characteristics of the pest, the nymphs suck the sap of the rice stem, leaf and ear, and the macula is produced in the affected area, and the tillering and development are severely inhibited, resulting in the death of the whole plant. In recent years, with the changes in the ecological environment of farmland and the change of crop layout, the pest of this insect has increased year by year.
Morphological characteristics
Adults are 8.5–10 mm long and 4.5–5 mm wide, oblong-oval, black-brown to black, with the mid-head and lateral lobes of equal length, the compound eye is prominent, and the beak is long enough for the hindpod basal nodes. The anterior corner of the dorsal plate of the forebreast is stabbed flattened to the side. The small shield is tongue-shaped, slightly concave or flattened at the end, almost as long as the end of the abdomen, and the lateral margins are slightly curved inward in the middle. The eggs are nearly short barrel-shaped, reddish-brown, 0,9×0.8 (mm) in size, with pseudo-ovoid rounded protrusions, surrounded by 40-50 small tooth-like respiratory sperm foramen; the egg shell mesh pattern has small incisions and is covered with white powder. Indyna nymphs have a brown head and thorax, a yellowish-brown or purple-red abdomen, a red node, and a reddish brown spot on the abdomen and dorsal area, with a body length of 1.3 mm. The 3rd instar nymph is dark brown to grayish brown, with small reddish-brown dots scattered on the abdomen, and the forewing buds are slightly exposed, and the body length is 3.3 mm. The 5th instar nymph has a light black head and thorax, a slight green belly, and obvious hindwing buds, with a body length of 7.5-8.5 mm.
