The Orange-tip (Anthocharis cardamines L.)

The Orange-tip belongs to the family of Pieridae, this spring butterfly flies in a single generation from mid-March to late May in Provence. This widely distributed butterfly frequents the woodland edges, woodland glades, wet meadows, watercourse edges, mesophilic meadows, grassy banks, road sides and more rarely the garrigue. The sexual dimorphism of the Orange-tip is very marked and apparent; the apex of the male's fore-wings carries the famous orange spots, bordered by a small black band (both sides). The upper side of the wings of the female Orange-tip is mainly white and resembles other white Pieridae although it has the same black band at the apex as the male. At rest, the Orange-tip closes its wings and its mottled green and white hind-wings ensure excellent camouflage. This underside, similar for both sexes, is characteristic of the Anthocharini tribe. After mating the female lays isolated eggs, preferentially at the base of the flower buds, selecting mainly isolated plants or ones that grow along the edge of fields or paths. In the Midi, the Orange-tip lays her eggs especially on the hairy rock-cress (Arabis hirsuta). The oblong egg incubates between 4 to 12 days, depending on the weather conditions and turns in two days from white to orange, and then becomes darker in colour. The caterpillar is polyphagous and at its 4th stage, the bicolourism becomes more visible, the ventral part remains green, flanked by whitish dorsal drawings. Mature, the caterpillar leaves the food-plant in search of a sufficiently rigid support for pupation. This twig must be able to endure winter conditions and support the chrysalis for about ten months. The curious "thorny" form serves as a camouflage. The Orange-tip overwinters as a chrysalis and it is not until the following spring that the butterfly emerges.
