After hatching, the larvae feed initially on the surrounding plant substrates. In a later stage of their development they prey on small insects, just as the adultsdo. After the last larval stage, the larvae pupate. The pupae are spun in a cocoon of silk and have long breathing tubes. | | |
| | The females lay their eggs directly on the excrement, or more rarely on decaying plant parts, where the substrate serves as a nutrient medium for the larvae who hatch one to two days later. The larvae go through 3 stages of development before they pupate. Pupation takes place in the nutrient medium or in the underlying soil. The pupae... | | |

They are often found (as adults or larvae) floating on the surface of salt water or brackish water (mixture of river and sea water). The adults eat rotten plant debris. They surface for air head first and trap air to breath under their wing covers (elytra) and "row" themselves along by alternating the hind legs, wiggling from side to side as they swim. Their eyesight is not very developed. The...
...he beetles to land on? reflective surfaces (wet or shiny car roofs, windows, etc.) having confused them with open waters.
After mating, the oviposition of the females happens in cocoons near the surface of water where the eggs are glued to water plants. Approximately 8-10 days later the larvae (with body lengths of 3-4 mm) hatch. They increase rapidly in size . The larvae feed (starting at the lastest three days after hatching) ) on smaller aquatic animals, and are even prone to cannibalism. In... | | |

Oviposition of the fertilized females takes place separately (in rarer cases in small groups) do you mean that the eggs are usually laid singly on the preferred food plants of the caterpillars, such as the cuckoo flower (Cardamine pratensis), bittercress (Cardamine amara), garlic mustard (Alliaria petiolata) and many different Brassicaceae (in former times: Cruciferae).

... (Alliaria petiolata) and many different Brassicaceae (in former times: Cruciferae). From the latter the female orange tip clearly prefer dame’s rocket (Hesperis matronalis), although this offers little food for the larvae. They prefer to visit plants in damp and half shady biotopes. 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.

| | .... Due to its appearance the caterpillar of the orange tip can be confused with that of the common brimstone butterfly (Gonepteryx rhamni), but can however be distinguished by its black warts. The caterpillar lives from June to August on its food plants, where it eats the flowers and the developing seed capsules. The most caterpillars can be found on tower mustard plants (Turritis glabra). When 2 caterpillars meet on a plant cannibalism can occur between the competitors due to limited food resources. They also eat Eggs from the same batch. | | |

At the end of July or in early August the caterpillars pupate with their heads upwards. Pupation occurs on the ground near the food plants or on the stalks or branches of other plants. The pupae are initially yellowish-green, later yellowish-brown or grey brown, and are shaped like a boat with a crescent-shaped head, which looks like a thorn on a plant. At the end of March or in early April, after approximately 10 months of rest in the pupal state, the adult orange tips hatch. The orange tip was Butterfly of the Year in 2004. | | |
| | 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 seems to have no fear of humans. Birds pose the biggest threat as they prey on the larvae when they are on their way int... | | |
| | 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.

| | Harvestmen live mostly in the bottom layer of humus and feed mainly on small Arthropods. They are found in hardwood forests, gardens, hedgerows, meadows and parks, some species live in dunes, heathland or moors. There, they graze dead plant parts, on which sit Arthropod corrosive. They can be encountered in larger numbers in natural hardwood forests, groves close to wetlands and forests where they break their hundreds in a confined space can be encountered where hundreds can be found ... | | |
