The miracle of life-the tragedy of the broad-winged wax cicada

Transparent sparse wide-winged wax cicada nymphs survive in groups

This year, whether it is , beetles , the most obvious reduction of beetles and beetles is less than that of span or 6span. span7span, this huge family of insects, like , the inhabitants of the ancient Loulan country, suddenly disappeared from their homeland. Fortunately, the larvae of the purple wax cicada are still common, which gives me a little comfort. What makes me even more relieved is that there are still many nymphs of the wax cicada, and many have taken off their "velvet coats" and transitioned to the adult stage, and some have already shed their first skins.

I am mainly referring to the wide-winged wax cicada The largest family of cicadas. Almost everywhere in this season. But seeing that they are about to mature, I feel a little bit sad for them. There are too many sufferings in their life cycle, so it is not too much to define a life of misery. If it hadn't been for them to maintain the continuity of the race with a huge number of reproduction, they might have disappeared from our sight.

The hyphae,Several or even dozens of them gather in groups to protect themselves. They especially favor the living environment of human beings. They mostly occur in environments close to humans, such as green spaces and parks in urban residential areas, and they are also concentrated on the edge of farmland in large rural areas. In cities, many people see them and rush to apply medicine, as if they would harm people. As a result, many transparent sparse winged wax cicadas died at a young age.

Wide-winged wax cicada nymphs are growing and molting

Only after the transparent thinning of the silky wax cicada, the velvet velvet coat can be removed several times. Eclosion, and this is the most dangerous period for them. All kinds of predatory insects prefer the prey that this activity is not so fast and easy to catch, so the bee fly insects always shuttle between the branches where they hide. .

The period before emergence is the most dangerous period for transparent sparse winged wax cicadas

Sexual strikes have made them a veritable rare species in some rural areas. I once read a paper discussing the harm of the broad-winged wax cicada to agriculture and forestry. I really don’t know where the scholar’s ​​argument comes from, but according to my observations, although the transparent and wide-winged wax cicada is a plant food from the nymph stage to the adult stage, their harm to plants is related to butterflies, Compared to insect larvae such as and lepidoptera, moths are negligible. For example, they are mainly parasitic on mulberry trees, wild sunflower and other plants in Dalian.Even on the plants where they have the highest concentration, no obvious signs of damage can be found.

(Mainly take a green area in the community where I live as an observation site) The final survival rate of the transparent sparse-winged wax cicada is only about 5%. How could such a silent and uncontested little insect provoke some people in this way? If I can contact the "expert" who wrote the thesis, I really want him to provide data on the area of ​​damage and the consequences of the observation target and the transparent sparse-winged wax cicada, so that the facts can support the conclusion of his thesis.

Occasionally transparent sparse winged wax cicadas also hide on the leaves of hairy cherry

, I think the reason is that they don’t understand this little insect too much, and they are often frightened by their young camouflage. This shows that our natural science education is still too far behind, and the natural science literacy of the whole people needs to be improved.

Wide-winged wax cicadas are very quiet, I don’t know why people want to kill them all.Only when there is a large-scale outbreak that endangers human health and safety and agricultural and forestry production, it is a "pest". When they exist properly in nature, they are only a link in the natural ecological chain and an indispensable link. If we eliminate the "pest" aphids artificially, then the ladybugs that feed on the aphids will be extinct, and the natural ecological chain will inevitably be broken. In fact, as long as aphids do not occur in an outbreak, they also have meaning. They feed many ants, and at the same time they also play a role in stimulating the growth of damaged plants. Therefore, we humans must have the necessary respect for any kind of life on earth, and we must never change nature with our own will.
