While most species of Silphidae can be found on animal carcasses, others choose fungus, rotting plants, healthy plants and faeces, some only for oviposition. The Silphidae and their larvae live and feed on carrion - necrophagous, on parts of plants - phytophagous, on faeces - coprophagous, or by preying on adult insects, insects’ larvae or on snails. Dendroxena quadrimaculata live off caterpillars, whi...
...eces - coprophagous, or by preying on adult insects, insects’ larvae or on snails. Dendroxena quadrimaculata live off caterpillars, while members of the genus Nicrophorus bury the corpses of small animals (mice, moles etc.) and dig an incubator for oviposition alongside them. The females form small balls out of the dead tissue with which they feed the larvae after hatching. Beetles of the genera Thanatophilus, Necrodes and Silpha also live on carrion, but without burying it. | | |

The females build individual brood chambers inside the nest using glandular secretions and leaf pieces. ) They deposit pollen and nectar in each brood chamber for the future larvae before they start laying eggs. After oviposition the brood cell is closed with a seal. The hatched larvae feed on their food stock for some weeks before they pupate.
Some species overwinter as larvae, others as adult mason bees. The latter are already active in March. The natural enemies of... | | |

Hylaeus reproduce either once or several times a year. The females lay their eggs in nests, which are constructed in hollow plant stems, dead wood or often in the galleries of beetles or other insects. After oviposition (egg laying) the nest is sealed. The larvae overwinter in the nests. Wasps of the family Gasteruptionidae are natural enemies of Hylaeus as their larvae feed on the brood of Hylaeus. | | |

Before oviposition occurs, the females fill the brood chambers with a puree of pollen and nectar, on which they lay their eggs ,in a small puddle of nectar. The hatched larvae feed on the puree until early autumn, thereafter they pupate within the brood chamber. ... | | |
| | Eggs are laid either individually or in smaller groups on living or dead plants and can number as many as 5000. Occasionally, the eggs are also stored directly on the soil.
Approximately 4-6 weeks after oviposition (egg laying), the larvae hatch. At the end of their abdomen is an apparature by which they move ( like inchworms ). If they encounter a spider, they jump onto it and drill through the skin at the joint until they are inside the spider. They th... | | |
| | Flat-footed flies feed on organic deposits on the leaves of trees and herbage. The females commonly lay their eggs on tree fungi. Oviposition also occurs on dead or decaying wood. The hatching larvae then feed on these materials. The larvae reach body lengths of 4-5 mm. Their yellowish to brown bodies resemble woodlice in shape and have appendages in different sizes depending on the s... | | |

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 la... | | |
| | 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 cylindric... | | |
| | Due to their camouflage Orange tips mate in April or May. At this time the male orange tips (can be observed frequently at hedges and in meadows on their search for the shy and inconspicuous females. 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 (C... | | |
| | After mating, the fertilized females lay their eggs in the nests of different bee and waspspecies, for example Heriades truncorum and Ancistrocerustrifasciatus. Occasionally, oviposition takes place in butterfly cocoons, as observed in the 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 ... | | |
