| Willow flea beetle | ...f 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 countryside, moist forests, forest edges, wet meadows, marshes, meadows and heathland are their preferred habitats. They can also be encountered in natural gardens and parks.

...ellowish and spindle-shaped.
The larvae hatch in summer. They are 5-6 mm long, black and resemble a small slug. The larvae live sociably on the same host plants (such as willow and poplar trees of the genus Salix or genus Populus) just like the adult beetles and often eat the leaves with the venes of the leaves remaining only. In late summer, the three-month development from egg to adult beetle is complete. The adult beetles overwinter under piles of leaves or in other protected places near the ground.

| | Robber flies | | ...e red-legged robberfly (Dioctria cothurnata).
Robber flies are, on average, 10-20 mm in length, the smallest being 3-4 mm and the longest 65 mm. What is remarkable about these flies are their long, strong legs which they use to capture prey.
Adult robber flies’ ways of living are as varied as their biodiversity. Robber flies can be encountered in different habitats, from forests to sandy areas.
Less is known about their larvae They live in soil or in the woods and, like the adult flies, feed on other insects and their larvae (mainly on scarab beetles’ larvae, or on the larvae of beetles which live in wood). The larval stage takes 1-2 years before the larvae pupate.
Adult robber flies ambush other insects in flight. For this purpose they perch and wait. . If an insect is flying in their vicinity, the robber fly flies up into the air, attacks and stings. | | |
| | | The larval stage for most beetle species is the longest period of their lives and can last several years, with the living of the larvae is often similar to the living of the adult beetles. The living of the larvae affects the duration of their larval stage.
In the Palearctic beetles mostly overwinter as pupa and slip off during the spring. Some species overwinter as adult beetles (for example: ladybirds and Hydrophilidae).
The most important natural enemies of the beetles are pathogens (viruses, bacteria, protozoa, fungi), parasites (Ichneumon wasps, tachina flies, Acarina) and enemies like birds, hedgehogs, shrew... | | |
| | This bug overwinters in the adult stage. It hides in fallen leaves, bark or in the hollow parts of plants. From May on the larvae hatch, which are green in colour and in July the adult stage is reached. The females lay their eggs on nettles on the upper side of the leaf stalks. Every year, a new generation emerges. | | |
| | Adult longhorn beetles feed on pollen, flower parts or tree juices. Some species prefer tree bark or leaves and the stems of cabbage plants. Other species don’t eat anything or are predatory. The life span of an adult longhorn beetle is anything up to 90 days, in many species less than 1 month. | | |
| | ...ere other plant material rots. During their development (3 to 5 years) they profit from the warmth created by the decomposition of the plant material. The mature larvae pupate in a cavity approximately the size of an egg, surrounded by a cocoon. The adult beetle hatches and remains in this dwelling for a few weeks. Adult rhinoceros beetles can be observed outdoors from June onwards. They fly at night. Their life expectancy is around 4-5 weeks. | | |
| | The adult Birch Catkin Bug overwinter. After mating, the female lays its eggs on leaves. The larvae live on deciduous trees, where they are very sociable and may occur in large numbers. In summer, the larvae become adult bugs. In autumn, they go in search of protected places and are often found hiding in walls after the leaves have fallen from the trees.
They pose no problems when encountered in areas inhabited by humans and simply die there after a few days. | | |
| Adult Anthophora and Amegilla are active from March to June. They are often visible on deadnettle (Lamium) or on other species of the mint family (Lamiaceae), as well as on borage (Borago officinalis) and species of the primrose family (Primulaceae).

...mbers with a puree of pollen and nectar, on which they lay their eggs ,in a small puddle of nectar. The hatched larvae feed on the puree until early autumn, thereafter they pupate within the brood chamber. They overwinter as pupae and hatch as adult bees in March. Among the parasites who feed on the brood of Anthophora and Amegilla is the oil beetle Sitaris muralis. In march, the female Sitaris muralis beetles place an egg on the fur of hatched male Anthophora and Amegilla.

| ... antennae are bright yellow. The top section? the upper surface? of their chest (thorax) is shiny black. Their scutellum is also light yellow. They have markings on the upper surface. The females have an ovipositor on the end of their bodies.
The adult flies have a life span of about 1 week and only feed on vegetables (phytophagous). Aside from the open air, they are mainly encountered in greenhouses. After hatching from pupae, the females start feeding immediately. They drill small holes in th...
...nus Liriomyza. The outer layer of the leaves remains intact.
After 4 days the larvae are fully developed and leave the leaves’ interior, through a slit, in order to pupate. The development from egg to pupae (reddish-yellow to brown in colour) to adult takes about 17 days.
Endoparasites are natural enemies of the Chrysanthemum leaf miner larvae, for example, the larvae of the ichneumon wasps Dacnusa sibirica and Diglyphus isaea. The ichneumon wasps lay their eggs in the larvae of the Chrysant... | | |
| The body of adult Sepsis fulgens is usually dark, with a metallic sheen and 2-4 mm in length. The abdomen is roundish with a "wasp waist" at the front and altogether the bodyresembles that of an ant. The wings (males’ 1.8 to 3.3 mm in length, fem...
... front and altogether the bodyresembles that of an ant. The wings (males’ 1.8 to 3.3 mm in length, females’ 2.7 to 3.4 mm ), are completely transparent with a dark spot at the top. Males can be distinguished by the shape of their front legs. Adult flies give off a peculiar smell.
