Top 20 Most Common Insects in Leeds

The heart and dart (Agrotis exclamationis) is a moth of the family Noctuidae. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. A familiar moth to many, it is considered one of the most common of the European region. It occurs throughout the Palearctic realm from Ireland to Japan. This is a quite variable species with forewings ranging from pale to dark brown but always recognizable by the distinctively shaped dark stigmata which give it its common name. The wingspan is 35–44 mm. The hindwings are whitish (compared with other common Agrotis species, the hindwings of this species are usually paler than in heart and club but darker than in turnip moth). This species usually has a dark area at the front of the thorax, visible as a horizontal bar when viewing the moth head on. The differences are not consistent however; they are highly variable in both colour and markings, and identification of atypical or worn examples may prove impossible without examination of genitalia. See Townsend et al. This moth flies at night from May to July and is attracted to light, sometimes in large numbers. It also frequently visits nectar-rich flowers such as Buddleia, ragwort and red valerian. The larva is brown above and grey below and feeds on a variety of plants, both wild and cultivated (see list below). This is one of the notorious cutworms and often severs or fatally damages plants at the base. The species overwinters as a full-grown larva in a chamber in the soil before pupating in the spring. ^ The flight season refers to the British Isles. This may vary in other parts of the range.

The brown hawker ( Aeshna grandis ) is a large dragonfly about 7 cm long. It is a distinctive species and is easily recognised, even in flight, by its brown body and bronze wings. At rest, blue spots on the second and third segments of the male's abdomen can be noticed; these are absent in female.The nymph has stripes on the side of the thorax and distinct banding on the legs.

It has a wingspan of 2.5 - 3 cm. The wings are greyish white with three irregular black blotches along the costa of the forewing, the largest in the middle. Occasionally, much darker (melanic) forms occur. In the typical form the ground colour is dirty whitish and the median band is almost or altogether obsolete in its posterior half.

Often confused for the ladybug, multicolored asian ladybeetle (Harmonia axyridis) is a separate species that, unlike the ladybug, is a household pest. It is considered particularly annoying for its habit of returning to places from which it is removed. One of the most variable species in the world, there are many different colors and patterns multicolored asian ladybeetle may display, making identification potentially difficult.

Contrary to what you may believe of its name, the gatekeeper (Pyronia tithonus) is a butterfly, not a heavily armored guard standing at an iron fence. The gatekeeper seems to have its own gate based on weather, as it cannot survive well in colder climates. It also survives through the two eyespots on the end of each of their wings, protecting them against bird attacks.

The common blue damselfly is named for the delicate blue color of the males, while the female is a pale tan. These insects are a crucial part of the ecology of freshwater habitats since they are mid-level predators that eat small larvae and invertebrates. In turn, they're preyed on by fish and larger larvae. This insect is highly susceptible to pesticide contamination of these freshwater habitats.

Forewing varying from whitish ochreous, through pale and dark grey to brownish grey, dark brown and black; a black streak from base below cell, another above inner margin near base, and a third, more strongly marked, along submedian fold between the claviform stigma and outer line; inner and outer lines pale, with dark edges; claviform small, dark edged; upper stigmata large, of the ground colour or paler, with pale rings and dark outlines; the orbicular varying in shape, generally oblique and elongate, sometimes shortened, and more rarely rounded; submarginal line pale, zigzag, preceded by black wedge-shaped marks, the terminal area, except at apex, darker; inner margin usually marked with white scales, developed beyond outer line into a more or less prominent pale patch reaching submedian fold; hindwing dirty greyish, with darker cell spot and veins, with a broad fuscous marginal border preceded by a dark outer line; — ab. pallida Fuchs is wholly whitish ochreous, with all the black streaks plain, the stigmata black edged; the central area and the terminal washed with brownish grey; hindwing whitish with an ochreous grey faintly marked border — in intacta Petersen the usual pale patch beyond outer line on inner margin is absent, the whole wing being suffused with grey or grey brown; — ab. obscura Th. Mieg. represents a suffused brown or grey-brown form; — infuscata Buch. White is a northern form with the markings more or less obscured and hidden by blackish suffusion, of which brunnea Tutt is a brown black offshoot; the extreme form of this, when all markings are lost in an intense black suffusion, is aethiops Tutt; in all these dark-suffused forms the hindwing is much darker, especially in the terminal. This moth flies at night. In the British Isles it is active from June to August with a second brood sometimes emerging in September and October. It is attracted to light, sugar and many nectar-rich flowers. The larva feeds at the roots of various grasses including tussock grasses, orchard grass, ryegrass, reed grasses, and fescues such as sheep's fescue. This species overwinters as a larva.

The silver y (Autographa gamma) has an interesting name that comes from the silver, y-shaped patterns on each of its wings. Patterns on those wings also provide for decent camouflage. Its colors can be different depending on the local climate. You may catch them in your garden given their love of taking nectar from flowers.

Red admiral (Vanessa atalanta) is a visually striking species of butterfly. Unusually territorial, males will compete for choice areas, and females will only mate with males that maintain their own territories. This butterfly is known for being particularly patient with human interactions, even to the point of perching on clothing or flesh.

Aphantopus hyperantus is a medium-sized butterfly with a wingspan of up to 3.5 - 4 cm . The wing upper and lower sides are solid brown with small, yellowish-rimmed eyespots. The newly emerged ringlet has a velvety appearance and is almost black with a white fringe to the wings. The number and size of the eyespots is variable, they may be missing on the upper wing surface. The eggs are pale yellow when first laid, but become pale brown.The caterpillars are about 2.5 cm long. They are gray or light reddish brown and have dark, reddish brown and very fine dots. Dorsally there is a dark longitudinal line, which is widened at the segment boundaries. Toward the rear, this line is more intensely colored. The head is darker and has several faint longitudinal stripes.
