Top 20 Most Common Insects in Naples

The painted lady is a migratory butterfly that spends part of the year in Northern Africa and then migrates to Europe during the warmer months. Although the adults feed on nectar from flowers, the larvae feed on the leaves of nettles and thistles.

The dotted border (Agriopis marginaria) is a moth of the family Geometridae. The species was first described by Johan Christian Fabricius in 1776. It is found throughout Europe, except the far north, and the Near East. The female of this species has only vestigial wings and is totally flightless. It is usually found resting on the trunks and branches of the larval food plants. The male has orange-brown forewings with a paler yellowish band and a row of dots along the termen which gives it its common name. The hindwings are whitish with faint fascia. Melanic forms are frequently seen. The wingspan is 36–42 mm. The adults are active from February to April, the male sometimes coming to light but not strongly attracted. The egg is ovate, greenish, becoming reddish on the upper side. The very variable larva is usually greenish-brown with dark cross-shaped markings along the back and feeds on a range of trees and shrubs (see list below). The species overwinters as a pupa. ^ The flight season refers to the British Isles. This may vary in other parts of the range.

Pachycnemia hippocastanaria, the horse chestnut moth, is a moth of the family Geometridae. It is found in most of Europe. The wingspan is 28–32 mm. Adults are on wing from April to May, and again in a partial second generation in August, usually with fewer and smaller moths. The larvae feed on Calluna species, although both the English and Latin names refer to the horse chestnut.

The wingspan of the moth is about 4 cm. Its head, thorax and forewings are very dark brown, but paler toward the wingtips. Sub-basal, median and postmedial indistinct waved lines are black. A curved submarginal ochreous line with ferrous colored lunuled found on each side of it. There is a marginal black lunule series. The hindwings are practically white. Tarsi bear black and white stripes.

The white-legged damselfly or blue featherleg (Platycnemis pennipes) is a damselfly of slow-flowing, muddy waters. It occurs from the Atlantic to Siberia and is often abundant throughout its range.

An unusually large and heavy species of moth, large yellow underwing (Noctua pronuba) is dreaded by gardeners for the larvae's habit of causing fatal damage to the base of virtually any herbaceous plant. Large migrations occur some years, but how those years are determined is not yet known. Its contrasting colors (yellow-orange and brown) are thought to confuse would-be predators.

Eristalinus taeniops can reach a length of 1.09 - 1.4 cm. These hoverflies exhibit a bee-like yellow-black drawing. The thorax has a metallic yellow-brown color and it is densely yellow hairy. Also the scutellum are yellow-brown colored. The abdomen is reddish-yellow, with transversal black bands. The compound eyes have five distinct, vertical, dark stripes. The wings are transparent, usually yellowish-brown at the base, while the halteres are brightly pale yellow colored.

The spring dor beetle (Trypocopris vernalis) is a beetle with a beautiful, metallic appearance. Despite their beautiful appearance, these insects are not in beautiful places. They are commonly found feasting upon the dung of various creatures, especially sheep and foxes.

The wingspan is 1.6 - 2.5 cm.

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.
