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. They overwinter as pupae and hatch as adult bees in March. Among the parasites who feed on the brood of Anthophora and Amegilla is the oil beetle Sitaris mura...
...arch, the female Sitaris muralis beetles place an egg on the fur of hatched male Anthophora and Amegilla.
During mating the eggs are transferred to the fur of the female bees and are thus transported unnoticed into the bees’ nests. The hatched larvae of the oil beetle feed on the food stores and on the brood of the Anthophora and Amegilla bees.

The brood cells are filled with a pulp of pollen and nectar by the females and afterwards they lay an egg on this mixture. A few days later the larvae hatch. The development of the larvae to the point of pupation takes a few weeks. The pupae overwinter. | | |
| | | The females lay their eggs on rotting plants, under bark or in reeds, using a special ovipositor which enables them to bore holes. 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. | | |
| | ...fulgens usually then visit dung-heaps where they await females for mating. The mating takes place at another location later on.
The female flies lay their eggs on dung-heaps or compost heaps. From the first or second day after hatching, the larvae begin feeding on feces or rotting parts of plants. At the end of their third larval stage the fully developed larvae turn into pupae. This happens in the dung or compost or in the soil below it. From egg to adult fly can take 14 to 32 days.
Parasitoid mites like Bonomoia sphaerocerae and Macrocheles insignitus are the natural enemies of Sepsis Fulgens. These ... | | |
| | 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 have a reddish surface. 14-32 days after the eggs are laid, the adult flies of the new generation leave their pu... | | |
| | The females possess special glands to produce fibres which they use to build cocoons under water. Air is kept in these cocoons for the larvae to breathe. Water scavenger beetles feed on plants and rotting substances. Their larvae mostly live predatorily at the bottom of water bodies. Water scavenger beetles are very useful because they purify the water. | | |
| | ...lay their eggs in. They bite the butterfly pupa and lay an unfertilised egg inside it. From this egg a male develops. If the females find a large pupa, they insert a fertilized egg in the same manner, from which a female develops. The hatched larvae initially feed on the blood of the butterfly pupae.
Later, they eat the whole insides of the pupae. After that the black slip wasp larvae pupate. 2 weeks later the young black slip wasps hatch and bite through the skin of the butterfly pupae. The adult black slip wasp overwinters, often behind tree bark. | | |
| | The larvae of velvet ants live parasitically in the nests of Aculeata, where they consume both the larvae of the hosts, as well as their food (nectar and pollen). Adult velvet ants are active from May to October in different habitats. In midsummer, they are often encountered en masse. | | |
| 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. Bi...
...reep 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 into the water and especially like to attack the juvenile dragonflies when they have just hatched from the excuvia. | | |
| ... lay several hundred eggs (which are generally larger than those of other blowflies) on rotting meat. The whitish, cylindrical eggs are 1. 6-1. 75 mm in length and 0. 5-0. 7 mm in breadth and taper at the front, while the posterior end is blunt. The larvae hatch after 1-2 days and in the first stage of development reach body lengths of 1. 8-2. 2 mm. They feed on the dung, carrion or garbage, in which they live. In the 2nd larval stage, they are 2. 7-3. 8 mm long. At the end of the 3rd larval stage, th...
...atch after 1-2 days and in the first stage of development reach body lengths of 1. 8-2. 2 mm. They feed on the dung, carrion or garbage, in which they live. In the 2nd larval stage, they are 2. 7-3. 8 mm long. At the end of the 3rd larval stage, the larvae are 13-14 mm in length and they then pupate. The pupae are 8. 4-9. 8 mm long and in size differ from pupae of other species of blow flies. The development time from egg to adult is approximately 38 days in total. | | |
