| Map | | The map (Araschnia levana) is a butterfly species in the family Nymphalidae. There are two generations a year whose adults look significantly different. The reason for this is to find in the different day lengths (sunrise to sunset) during the development of both generations’ caterpillars. The reason for this is the differing amounts of daylight available during the caterpillars’ development. The name of the butterfly is derived from the marking on the underside of the wings, which resembles a map. This butterfly is fou... | | |

The larvae live in soil, some also in water. The larval phase ( in total 3 stages) lasts for about 8 days. In Europe the adult flies take 2 to 3 weeks to hatch. The high reproduction rate of Muscidae (about 8 generations per year), is due to the large number of enemies they have - and not due to a dramatic increase in their numbers.
A number of species (outside Europe) are known to transmit diseases such as dysentery, cholera, hepatitis, polio, anthrax, typhoid f... | | |

| ...eda, cress, mustard and radish - which hatch after a maximum of 8 days. The caterpillars are solitary. After moulting four times they pupate. If the pupae do not hibernate, the new butterflies emerge after 10 days. The small white produces 2 - 3 new generations a year. | | |
|
| The caterpillar is bluish-green with white stripes. This species produces 2 new generations a year. The eggs are laid on wild grasses, in May or June, and again, in August. The caterpillars hatch from their eggs after about 10 days and feed on the wild grasses. They are nocturnal. The caterpillars of the first generation develop into adult... | | |

| The common blue is found at nearly all altitudes and in almost all biotopes. They are active from May to October and produce 2 - 3 new generations per year. Their caterpillars feed on clover, restharrow and broom. They overwinter. | | |
|
| The silver Y is found almost everywhere, but prefers farmland and gardens. The adult moths eat nectar from thistles, phlox and petunias. The silver Y produces several (overlapping) generations a year. The caterpillars, which feed on clover and various vegetables, overwinter in a kind of cocoon. | | |

|
| The small tortoiseshell produces 2 to 3 new generations a year. They can be encountered from March to October. They overwinter in protected places. Egg-laying occurs after overwintering, on the undersides of the leaves of the larval food plants, grand nettle, for example. A clutch comprises approximately... | | |
