Top 13 Most Common Insects in Kanazawa

Bombus ignitus is a large bee characterized by a medium length tongue. Females have black bristles that cover the back of the thorax and the mid-legs. The abdomen is separated into five tergum. Starting from the thorax, the first three terga are black in color, whereas the fourth and fifth terga are orange-red in color. Males are characterized by golden yellow bristles that form two bands on the anterior and posterior thorax. Like the female, the male has an abdomen separated into five tergum. Starting from the thorax, the first two terga are golden yellow in color, differentiating males from females. The third tergum is black in color. The fourth and fifth terga, like the female, is orange-red in color. Compared to the female, the male compound eye is small. The antenna of males are shorter than the antenna of females, reaching only to the base of the wings. Compared to the males of other bumblebee species, the males of B. ignitus have greatly broadened penis valves that flare outwards to form a funnel shape. The queen has a body length of 19 mm. Workers have a body length of 15–17 mm. Males have a body length of 17 mm.

Large brown cicada are usually about 6 - 6 cm long, having a wingspan of roughly 8 cm.

Female black-and-white spiny spider are 6 - 9 mm wide and possess a hard, shiny abdomen armed with six black conical spines. The upper surface of the abdomen is white to yellowish with variable black or dark brown markings and sigilla. Males are much smaller at 3 - 4 mm and in place of spines have small bumps on their abdomens.

The hawthorn shield bug (Acanthosoma haemorrhoidale) is a common European shield bug. Its chief food is haws, the fruit of the hawthorn tree, but adults can overwinter on a diet of leaves, and individuals can be found on many potential food plants, including pedunculate oak, sessile oak and whitebeam. They may grow up to 17 mm (0.67 in) long, and are camouflaged in shades of green and brown. Like many so-called "stink bugs", they may release unpleasant odours when disturbed.

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.

The adult males reach 2 - 4 mm in length, while females are 7 - 8 mm long. The two pairs of the front legs, used for hunting the flower-feeding insects, are more developed than the rear ones, which have a predominant motor function. Mature males have a black abdomen with two white marks. In mature females, the background colour of the abdomen can be red, yellow or white, with a black pattern which has been noted for a certain resemblance to the silhouette of Napoleon. Prosoma and legs are black or dark brown.

The impatiens hawk moth can be considered a pest among commercial and residential gardeners. Both the moth and caterpillar feed on several flowering plants, including fuchsias and the Australian native violet. Adult females lay their eggs on the plant’s foliage, ensuring the hatching larvae have a ready food source.

Stictopleurus punctatonervosus can reach a length of 0.26–0.35 in. These bugs have a regularly punctuated pronotum, a banded connexivum and a rounded tip of the scutellum. The body is gray-brown to black, while the abdomen is often greenish. In the anterior margin of the pronotum there are quite difficult to discern dark marks similar to two half circles or to reading glasses.
