Top 20 Most Common Insects in Richmond upon Thames

It rests with closed wings when not in flight.

Melanargia galathea has a wingspan of 1.8–2.2 in. In these medium-sized butterflies the upper side of the wings is decorated with white and gray-black or dark brown markings, but it is always gray-black or dark brown checkered in the basal and distal areas. The underside is similar to the upper side but the drawings is light gray or light brown. On the underside of the hindwings is present a row of gray eye spots. The males and the females are quite similar, except that some females may have a yellowish nuance on the underside of the wings. The larvae are a lime-green colour, with a dark green line running down the middle of their back. The caterpillars are about 3 cm long. They are green or yellow with some lighter and darker narrow longitudinal lines. The head is always light brown.

The greater stag beetle ( Lucanus cervus ) is popular with insect lovers. The male individual is known for the impressive jaws that look like antlers of a deer. In contrast, females do not have jaws and are much smaller. The adults feed on juices and tree saps while the larvae eat wood. By the way, greater stag beetles are considered a pest in the Middle East where they dig into the root systems of date palms, affecting the date crop.

The silver, comma-shaped marked on the butterfly’s wings give it the common name the Comma. It is a common butterfly in southern Britain that was once on the verge of extinction in the 1930s. The butterflies are often found at the edge of forests, close to meadows with plenty of nectar-rich wildflowers.

Ochlodes sylvanus has a wingspan of 28–32 mm, which is similar in size to Chequered skipper. Although called "large" this is still a relatively small butterfly and not much larger than either the small or Essex skippers. The body is rather squat. The antennae are hooked at their tips. The upperside of the wings is orange-brown with a brown border and some lighter spots. The underside of the hindwings is greenish-yellow, marked with sparse yellow spots. The male has a broad scented androconial dark line across the top of the forewings. On the hindwings of the females there are brighter square marks. When the wings are opened, the forewings are obliquely folded, masking the hindwings. The faint chequered pattern on both the upperside and underside, and also the hook-shaped antenna tips, help to distinguish the large skipper from these two orange skippers. The Lulworth skipper also has patterned wings, but does not have the hooked antennae. The caterpillar can reach a length of 28 millimetres (1.1 in). It has a large blackish-brown head and a bluish green body, with a dark line down its back and a yellow stripe along each side.

Small and colorful, small tortoiseshell (Aglais urticae) is the national butterfly of Denmark. However, it is capable of surviving anywhere the common nettle leaf may be found, which the larvae of this species depend on. Once among the most common butterflies in Europe and temperate Asia, this species is experiencing rapid declines for reasons still being investigated.

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.

Interestingly, individuals belonging to orange tip (Anthocharis cardamines) occupy different habitats depending on gender: the males inhabit the edges of forests, whereas the females prefer meadows. When laying eggs, females release pheromones to deter other females from laying eggs on the same flowerhead. They are picky about choosing their host plants, and females will avoid plants not fully exposed to sunlight.

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.

The holly blue is a popular visitor to gardens in the southern portion of the British Isles where the butterfly gathers in large number. Unlike some species, females lay two broods in the spring and summer. Spring female holly blue butterflies are identifiable by the bands on their wings that are lighter than those from the summer brood.
