| The abdomen is wasp-like at the front like an ants. The rear end is often peaked. The wings move up and down almost constantly. They are transparent but have a dark patch close to the outer edges. Their legs are partially covered with bristles. Due to their appearance Sepsis violacea can be easily confused with other species of Sepsidae. | | |

| ...More than a hundred eggs ( in separate groups of 20 or more) may be stored on the underside of leaves. After about one week the larvae hatch. The rear body of the larvae is beige or tan in colour. . Their heads, chests and three atrophied pairs of legs, are dark brown to black. They mature rapidly and in the last larval stage (about two to three weeks after hatching from the eggs) they pupate on the food plants One week later the beetles are fully developed and leave the cocoon. They overwinte... | | |

| ...ong metallic sheen, which is bronze, copper, blue, dark green and (more rarely) black in colour. The metallic blue-green to blue or black forewings (elytra ) have clearly visible dots, which run in multiple rows lengthwise. The head, scutellum and legs are a similar colour to the body but diffusely spotted have a scattering of dots. At the rear end of the body is a defensive gland, whose secretions determ both macrophages and enemies as also have disinfecting effects.

| Each segment of the abdomen has dark brown bumps and dark brown bristles at the edges and in the middle. Their glands are dark brown and without hair. Their legs (3 pairs) are glossy dark brown to black. A few weeks after hatching, the larvae pupate on their food plants. One to two weeks later, the new generation of beetles hatch. Brassy willow beetles overwinter in the soil as adults.

| Willow flea beetle | | ...d and oval shaped body has a metallic sheen. The entire upper surface area of the females is greenish-gold in colour; that of the males is greenish-blue, blue or purple. Longitudinal rows of dots are visible on the forewings (elytres). The brown legs to the ankle are much thicker in the upper section of the rear pair, with which the willow flea can jump very far (up to hundred times its own body length).
The life expectancy of the adult beetle is 8-9 months. They are usually found in the co... | | |

| The legs of the southern hawker are strongly built and are used for capturing prey. The wings can move independently of each other which makes rapid changes of direction in flight possible. The wings haveweak blue pterostigma. | | |
|
| The legs of the rabbit hutch spider are red in colour with brown rings. Due to their appearance they can be confused with Steatoda castanea.
The rabbit hutch spider can live several years. In Central Europe they tend to stay in one place and are found... | | |

| Arachnids, in contrast to insects, have 8 instead of 6 legs. Instead of compound eyes arachnids have 8 simple eyes. The head and chest are one unit (prosoma). The prosoma is followed by the abdomen which is not divided and mostly appears in a bigger size. They are a member of the subphylum Chelicerata havin... | | |

| ...ve segments. Dot eyes (ocelli) are not existing on them. The thorax (chest) has no continuous, V-shaped suture, as in the case of mosquitoes (Tipulidae). The wings of the females are black in colour and almost reach the end of their abdomen. The legs of the Chaoboridae are formed like stilts. | | |

| ...face which are capable of improving their ability to detect vibrations. The chest (thorax) is very arched. The wings are well developed and are posited roof-like on the abdomen in resting position. When at rest, these midges stretch their front legs out forwards free of their bodies and move them convulsively. Chironomus atroviridis have a life expectancy of only a few days. They feed on honeydew or nectar. | | |
