Top 20 Most Common Insects in Abano Terme

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.

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.

Despite its common name, only male specimens of common blue butterfly (Polyommatus icarus) can accurately be described as blue; the females are predominately gray-brown, with only a dusting of blue and a scattering of orange spots. The adults live for only three weeks before dying.

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.

Its slow and floating flight pattern makes it easy to identify the scarce swallowtail as it soars over gardens, orchards, and scrublands. The butterfly has a large presence across Europe, the Middle East, and Asia. The adult lifespan is brief, only two or three weeks. Planting flowers like blackthorn can encourage the butterfly to visit a garden.

It is a fairly large dragonfly (the length of 4.5 - 5 cm, 3 - 3.5 cm abdomen, rear wing 3.5 - 4 cm.) with relatively broad, flattened abdomen, but not as broad as to chaser species. With age, adult males develop extensive blue pruinescence on their abdomen, offset by yellow lateral patches. The middle lobe of the pronotum is large and notched in the middle. The chest is yellow or yellowish-brown. The base of the hind wings do not show a dark opaque spots. The pterostigma is dark brown or black. On the front wings pterostigma 2 - 3 mm long. Anal appendages are black. The females and immature males are a deep yellow color, with wavy black lines dorsally on their abdomen. Males and females have the costal vein (the leading edge of the wing) yellow or black.

Ischnura elegans can reach a body length of 2.5 - 3.5 cm and a wingspan of about 3.5 cm. Hindwings reach alength of 1.4 - 2 cm. Adult male blue-tailed damselflies have a head and thorax patterned with blue and black. There is a bi-coloured pterostigma on the front wings. Eyes are blue. They have a largely black abdomen with very narrow pale markings where each segment joins the next. Segment eight, however, is entirely pale blue. At rest, the wings of most damselfly species are held back together, unlike dragonflies, which rest with their wings out flat. The thorax of juvenile males has a green tinge. Female blue-tailed Damselflies come in a variety of colour forms.Juveniles may be salmon pink, form rufescens; violet, form violacea and a pale green form. The colour darkens as the damselfly ages. Mature females may be blue like the male, form typica; olive green thorax and brown spot, form infuscans or pale brown thorax and brown spot, form infusca-obseleta.

This is a large damselfly with a total length of up to 1.9 in and a hindwing length of up to 1.4 in. Male and female are variable in color and pattern. The male has translucent wings which each have a broad, dark iridescent blue-black spot (or band) across the outer part. On immature dragonflies the spot is dark brown. The body can be a metallic blue or bluish green or a combination of both colours, depending on the time of year and location. The dark wing patch of the male starts at the nodus (the slight dip midway down the upper edge of the wing) but can reach up to the wing-tip in southern races.

It rests with closed wings when not in flight.

The speckled wood (Pararge aegeria) prefers to live in damp, dark woodlands. Unlike other butterflies, it's more active in shadier habitats rather than sunny ones. Males often fight over a perch, spiraling up to the treetops until they determine a winner. These perches are where the males find passing females.
