...hout 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 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 Ju...
...he 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 weeks later (in July and August), the adults of the 2nd cherry slug generation hatch, mate and lay eggs. The larvae (cherry slugs) are active from September to October. They also pupate... | | |
| | Adult Tachina fera feed on the nectar of flowering plants and on honeydew, while their larvae live off the body tissue of different caterpillars. The females lay their eggs near the caterpillars. The larvae immediately hatch from their eggs and penetrate the host caterpillars. The caterpillars die because the larvae feed on their inner tissue. The larvae are parasitic on the caterpillars of the gypsy moth (Lymantria dispar), the black arches (Lymantria monacha), and the pine beauty (Panolis flammea). | | |
| | | 4 to 5 weeks after hatching, the development of the nymphs is complete. The winged juvenile bugs mate very quickly. Egg laying by the first new generation occurs in late June / early July singly in the leaf tissue of herbaceous plants. The nymphs hatch in midsummer. The specimens of the second annual generation during September turn over to the winter host plants. As adults, they for overwintering lay their eggs in the bark tissue of their host plants and the first new generation hatch the following year.

The young caterpillars, which hatch after a few days, are gregarious and live in self spinned tissue. At the end of the larval period, lasting 1 to 2 months, they are living solitarily or in small groups. The caterpillars then pupate. The pupae are brown or light green with shimmering patches and are covered in spines. 12 days after pupating the sm... | | |

| | The larvae of rose leafhoppers are cream coloured. Rose leafhoppers and their larvae pierce the leaf tissue and suck plant juices from the underside of rose petals. The rose plants initially show a fine, white and yellow mottling on the leaves. Rose leafhoppers usually start sucking along the leaf veins and later spread out onto the whole leaf. After a wh... | | |

They drill small holes in the top surface of plants’ leaves using their ovipositors and suck up liquid with their mouth parts. The damaged areas on the leaf tissue (which also enable bacteria and fungi to penetrate into the plant) are clearly visible as yellowish stains.
The males live on nectar or honeydew but they can live without nutrition until they mate. The females lay their eggs on the food plants o...
...d of the third and last larval stage the bodies of the larvae can reach lengths of up to 3 mm. The bodies are yellowish-white in colour and have no legs. The larvae remain in the leaf and bite twisting (serpentine like) passageways into the cell tissues by moving their mouth hooks up and down. Hence the English name "Serpentine leafminers" for the genus Liriomyza. The outer layer of the leaves remains intact.
After 4 days the larvae are fully developed and leave the leaves’ interior,... | | |
| | They breathe in the water using a special tissue in their rectum. When the larvae are fully developed some time in June, they creep out of the water along a plant stem and shed their outer skin (excuvia). When their wings have dried, they fly off as adult dragonflies. The southern hawker se... | | |
| | The female leaf-miner flies have an ovipositor at the end of their bodies. The adult Agromyzidae and their larvae live purely on vegetable substances (phytophagous) feeding on leaf tissue or other plant parts; the males live mainly off nectar and honeydew.

The eggs are very small and transparent and are sunk deep in the leaves’ tissue (usually on the underside). The eggs overwinter there. | | |
