Around 250 eggs are laid separately. 2 - 3 weeks later the solitary caterpillars hatch. During the day they stay on the underside of the leaves. The larval stage lasts 6 weeks and then the caterpillars pupate. The pupae are striking; the middle is constrictedly built and has a hump with shiny, metallic patches on the front and back. . The second generation of comma butterflies overwinter as adults. | | |

At the hind end a whitish tail boom is to see in the early larval stage. The caterpillars have stubby feet and are characterized by their excellent camouflage in the grasses where they live. | | |
| | | From April on, the larvae hatch. First they suck juice from the fresh leaves and the shoots of their host plants. The larvae (nymphs) are light green to deep green in colour and have orange-spotted antennae. In the 2nd to 4th larval stage, they swop over to herbaceous plants (potatoes, beets, strawberries, etc. ). | | |

The hatched larvae (nymphs) are a variety of colours and have no wings at first. These grow from the 3rd larval stage on (after the 2nd moult). The young bugs have their defense glands on their backs. In September the development of the nymphs is complete and after the last moult they emerge as fully developed adult bugs. | | |

The larvae breathe with the help of tube-like elongated openings. At the end of the last larval stage, the larvae pupate inside their outer skin. Within the chrysalis, the Scatopsidae breathe through tubes, which branch off from the thorax. | | |

Their markings and shape changes after each moult. In the first larval stage (which lasts 3 days), they remain sitting in groups next to their empty eggs without eating. In this way the tiny larvae can combine the power of their defense secretions and thus ward off their predators (ants, etc) much more efficiently. | | |

Approximately 24 hours after hatching the larvae moult and thus reach the 2nd larval stage. After another 3 days, and 2 further larval stages, the development of the maggots ( now brownish in colour and about 3 mm in length ) is complete. They develop within their third skin into a barrel-shaped pupa and remain there for 4 days. After that, the adult flies of the new generation hatch.

The caterpillars are resistant to the cold winter and in the 3rd Larval stage are to find on grass. The larvae continue eating in the spring. In May, they pupate in a parchment-like cocoon, with strong bristles. The pupa hangs from a blade of grass, is black and red in colour and darkens wit time. In June, the adult drinker h... | | |
