Top 13 Most Common Insects in Luohe

Vespa bicolor, the black shield wasp, described by Johan Christian Fabricius in 1787, is a species of hornet which has been found to be the pollinator of an orchid, Dendrobium sinense (syn. Dendrobium christyanum), found only on the Chinese island of Hainan. Vespa bicolor also preys on honey bees, which it feeds to its larvae. The orchid produces a chemical that mimics a honey bee pheromone and attracts this predatory wasp. Vespa bicolor is the most common species of large wasp in Hong Kong, along with members of the genus Parapolybia. It is found in a wide range of environments and can be found near human dwellings.

The yellow-spotted stink bug has a wide distribution across Asia. In China, the insect is a pest to more than 57 plants, including fruit trees. It can damage plants and reduce crop yields. Adults overwinter in natural and manmade shelters like building crevices and underneath tree bark, emerging in the spring to feed on the tree’s new growth.

Regardless of sex, the hornet's head is a light shade of orange and its antennae are brown with a yellow-orange base. Its eyes and ocelli are dark brown to black. V. mandarinia is distinguished from other hornets by its pronounced clypeus and large genae. Its orange mandible contains a black tooth that it uses for digging. The thorax is dark brown, with two grey wings varying in span from 35 to 76 mm (1 ⁄8 to 3 in). Its forelegs are brighter than the mid and hind legs. The base of the forelegs is darker than the rest. The abdomen alternates between bands of dark brown or black, and a yellow-orange hue (consistent with its head color). The sixth segment is yellow. Its stinger is typically 6 mm (⁄4 in) long and delivers a potent venom that, in cases of multiple hornets stinging simultaneously, can kill a human.
