- The biology of birds in the wild
- 1 – Birds in Animal Paradise
- 2 – The evolution of birds: a look at their fosil past
- 3 – Specification and systematics are important components of biology:
- 4 – Bird feathers: what, where and why
- 5 – The art of flying, how birds do it
- 6 – Fuel for the bird engine
- 7 – Every bird sings as it is beaked
- 8 – From beak to cloaca
Habitat: Grassy, rocky erosion slopes. Often in warm, dry places with shrubs and lots of flowers. Nutrient-poor grasslands and calcareous grasslands.
Appearance: Europe: Iberian Peninsula, Sardinia, Corsica, Sicily, through France (except NW and NE) to Denmark (only in Zealand and Bornholm), Balkans, Greece. Extinct in Belgium. Extremely rare butterfly in the Netherlands as a vagrant.
Flying time: May – June / July – end of August (usually two generations).
Characteristics: Wingspan 24 – 28 mm.
Life cycle: The host plants of the Oberthür’s Grizzled Skipper (Pyrgus armoricanus) mainly belong to the Rose family (Rosaceae). It prefers Strawberries species, such as Creeping cinquefoil but occasionally also uses Dewberry and Wild strawberry. Whereas most skippers feed on grasses, the caterpillar of this species specifically feeds on these herbaceous plants. The eggs are laid on the flowers of the host plants. As a young caterpillar (second stage of development), it overwinters among dead leaves on the ground. The butterflies feed on nectar from various flowers.
