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. | | |
| | The young adult alder leaf beetle leaves its pupa in August and lives off the leaves of various trees and bushes until the end of September. These include alder (Alnus), willow (Salix), poplars (Populus), birch (Betula) and hazel (Corylus). At the end of September - beginning of October the alder leaf beetle hides in the ground, w... | | |
| | | In late April - early May, it appears on alder leaves once more, in order to start the so-called "maturation feeding". Alder can release hormones, which lower digests the beetle and thus forces it to change host. In this way alder are protected from excessive damage to their leaves. The alder leaf beetle then evades on other alder, willow, poplar, hazel, other fruit trees and herbs. These beetles often occur here in great numbers, which can kill younger trees and can limit growth in older trees. | | |
| | ...Food plants are chosen particularly because of their ethereal oil (mustard oil) content, which the females detect using chemosensors, which are on their forelegs. In order to avoid egg laying on the same plant by other orange tips, the female leaves odoriferous substances (pheromones) on the leaves.

| | The andromeda lace bug can multiply in large numbers and appears en masse. The bugs cause mottling on the leaves of plants. Egg-laying is carried out with the aid of an ovipositor. The eggs are very small and transparent and are sunk deep in the leaves’ tissue (usually on the underside). The eggs overwinter there. | | |
| | ...which they suck from the flowers of the thistle (Cirsium) or other flowering plants like butterfly bush (Buddleja davidii). After mating, the fertilized females seek out the food plants of the larvae where they lay their eggs on the upperside of the leaves. The eggs are shaped like a cone, grooved, and greenish-grey in colour. They remain on the leaves for 3 to 5 days before the larvae hatch. When the larvae (caterpillars) have hatched, they build a tissue on the leaf, which initially covers the tip and then the whole leaf, under which they can eat undisturbed. The web, however (as in the case of ... | | |
| | The caterpillars appear from June to July and from August to May in the following year. They live (two generations at once) in a web on the upper side of the leaves of their food plants (including lichwort, comfrey and stinging nettle), and eat the leaves down to the skeleton. At the end of their development, the larvae pupate in a thick, white cocoon inside a leaf or near the veins on the leaf surface, causing the leaf to roll up. The pupae are yellowish-brown and overwinter. | | |
| | There are 6 different kinds of spear-winged fly larvae and they are shaped like wood lice. They have flat backs and 2 pairs of bristles on their heads. They live on the ground, amongst dead leaves, or in dung or rotting vegetation. They can even be found among the leaves of Brussels sprouts (Brassica oleracea) or white beets, especially in wet weather. The larvae feed on fungal threads (hyphae), algal cells, pollen, soil particles and substrates, which they find in excrement. They also prey on the larvae of bark be... | | |
| ... forests and gardens. Depending on the weather, it produces 2 or 3 new generations a year. Reproduction is normally parthenogenetic (without males). The females of the spring generation leave the soil in early May and lay their eggs, in June, on the leaves of different plants, such as cherry, pear, juneberry, mountain ash, hawthorn, quince, birch or roses. They scratch into the leaf tissue with their ovipositor, forming a small pocket in which a single egg is deposited. After 2 weeks, the larvae hatch...
...ich a single egg is deposited. After 2 weeks, the larvae hatch and crawl sluggishly on top of the leaf and eat the tissue under scraping. They skeletonize individual leaf parts without the venation (ribs, leaf veins) and the lower epidermis. The dry leaves go brown or roll up. The larvae (cherry slug) produce no more mucus in the final stage of their development. In July, they drop from the leaf and immediately create an egg-shaped tissue below the soil’s surface, in which they quickly pupate. About 2... | | |
| | Meiosimyza rorida are active from May to October in Central Europe, and prefer to live in the herb layers of deciduous forests, where they can be encountered moving slowly on leaves and stems. When disturbed, they hide. Females lay their eggs in rotting leaves, which the larvae feed on after hatching. | | |
