The prey is then kneaded into a pulpy mass which can be sucked up by the larvae. This takes 2-3 minutes. Finally the larva leaves the emptied skeleton and creeps forward back into the water. Cannibalism can become so prevalent among the larvae that they prefer to eat each other than to attack other insects. | | |
| | The sage leafhopperscan cause many herbs, including rosemary, lasting damage. Their sucking the leaves causes white or yellowish spots, and severe infestations of these insects can lead to crop failure. | | |
| | | ...arance, Chrysolina Polita can be confused with poplar leaf beetles (Chrysomela populi). Chrysolina Polita are encountered from March to October in different habitats, up to subalpine altitiudes. . Both the adult beetles and the larvae feed on the leaves of various plants, such as mint (water mint, cat mint), sage, or oregano.

| | Mating occurs from April on. Egg laying takes place a few days later, on the food plants of the larvae. 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 w... | | |
| | The brassy willow beetle is active from May to September. It mainly feeds on the leaves of poplars and willow trees. The females lay their eggs on the food plants of the larvae, which are the same as those of the adult beetles.

| | In May - June, matingtakes place. Oviposition also occurs in May - June in clutches of 60-70 eggs, which are laid on the lower surface of the leaves of the food plants of the hatching larvae. A female can lay up to 900 eggs. The eggs are approximately 0.5 x 0.9 mm in size, oval to cylindrical in form and ochre-yellow-orange in colour. | | |
| | ...ial grip, the male spiders avoid the female’s deadly bite and leave after mating. In order to store the fertilized eggs, females produce a dark green cocoon , and encase it in a fine white web. . The cocoon is attached to parts of plants (mostly leaves) and is guarded and protected against predators by the mother until the young spiders hatch, which takes about 100 days. | | |
| | Some species of lace bugs overwinter as adults. After mating, the fertilized females use their ovipositor to lay their eggs almost exclusively on the underside of the leaves of the food plants of their larvae (nymphs). The eggs of some species spend the winter there. The hatched larvae have longer or shorter thorns depending on what species they are. The typical lace like structure of the upper body is absent. In the fi... | | |
| | Female worker european hornets live for 3-4 weeks, drones,1-2 months, and the queen, up to 14 months. The queen, is the only member of the colony who overwinters. In the middle of April she leaves her hiding place and at the beginning of May,starts to establish a new nest. To this end she first builds a honeycomb, which she covers with a paper-like mass made from chewed wood. The queen lays fertilized eggs in this honeycomb. After t... | | |
| | ...iking characteristic is their long, segmented antennae, which often point backwards and may exceed the length of the body. They resemble ibex horns hence this insects name. As the antennae are so long, they must be anchored stably to the head which leaves little space for the eyes. In many species therefore, the eyes grow around the base of the antennae from behind. The bodies of these insects are elongated and are often larger in the males. Although sometimes the opposite is true. | | |
