Caterpillars often eat their own egg shells after hatching, and then feed on leaves, pine needles, flowers, seeds or fruits. Some caterpillars live as social parasites with ants. | | |
| | Egg-laying (up to several hundred eggs in a lifetime) is done with an ovipositor in moist soil orin the mud at the bottom of a body of water. The larvae reach body lengths of about 50 mm and live on plant roots, which they eat. They pupate in the soil or in rotten wood. Crane fly larvae can cause significant damage to crops. | | |
| | | ...nizable simple eyes. The threadlike antennae are about 4 mm long, yellowish-brown in colour and have club-thicked outer limbs. The mandibles are strongly developed. In the area of the mouth opening there are 2 tube-like appendages, which are used to eat. | | |
| | ... colour sometimes with a green shimmer. The head is light coloured with a central marking in yellow, gray, brown and reddish-brown tones. Their two large compound eyes are brown in colour. Their mouth parts are atrophied because they mostly do not eat and live of fluid. The surface of the thorax is yellowish, reddish and whitish in colour and has a wide, somewhat darkened median stripe, in which a bright line runs lengthwise. The scutellum (small triangular plate on the thorax) is bright tur... | | |
| The Pear Sawfly prefers habitats such as 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,...
...uneberry, 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 develop...
...eaf 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 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 Oct... | | |
| | ... case of the small tortoiseshell (Nymphalis urticae). Usually one egg is placed in each nest. Egg-laying often takes place in the nests of solitary bees of the genera Hylaeus and Osmia. A few days later the larvae hatch from their eggs. Firstly they eat the eggs or larvae of the host animals and later on any food supplies found there. | | |
| | After mating, the fertilized females lay their eggs at the base of grasses (Poaceae). After hatching, the maggots eat their way into and through the young sprouts and later feed on the young leaves of the grass plants. Further growth of such plants can be disrupted by this, or even prevented. The damage patterns on grass plants vary. Ragged, cracked leaves, are oft... | | |
| | After mating, the fertilized females lay their eggs singly on bumblebees, ambushing the workers in flight. They cling to the host animal and lay their egg between the abdominal segments. The larvae hatch quickly and then eat their way into the abdomen of the host and hollow it out gradually. Sicus ferrugineus larvae pupate and overwinter in the hosts. | | |
| | The larvae hatch after 1 to 3 weeks. They are 2 – 4 mm in length and eat tunnels to the soft cambium (layer between the bark and sapwood). Here, they take in nutrients (vitamins, minerals) with the tree sap. Once they reach the cambium layer, they overwinter. The following year, before eating, they penetrate into the harder sapwood. Here they overwinter for the second time. | | |
| | Acorn weevil larvae are 9 - 10 mm long. Their bodies are yellowish-white in colour and without legs. The head is reddish-brown and lacks eyes. The larvae eat out the core of the acorn. In autumn, when the damaged acorns fall from the tree, the larvae, which have now reached their full size, bore their way out and dig into the ground, where they settle themselves in small chambers about 250 mm beneath the surface of the ground for the purpose of overwintering. In the following spring, the larvae pupate in their chambers. They leave the pupae in May or June as adult acorn weevils. | | |
