Soie qui s%C3%A8che

Borocera cajani is a species of moth in the family Lasiocampidae. It is endemic to Madagascar and is known for its economic importance due to its role in the production of wild silk, commonly referred to as Malagasy silk.

Taxonomy

The species was first described by the French entomologist Jean Baptiste Boisduval in 1833. It belongs to the genus Borocera, which includes several other species of silk-producing moths.

Description

Borocera cajani exhibits sexual dimorphism, with males and females differing in size and coloration. The wingspan of the males ranges from 40 to 50 mm, while females are larger, with a wingspan of 60 to 70 mm. The moths have a distinctive brownish coloration with various patterns that provide camouflage against predators.

Life Cycle

The life cycle of Borocera cajani includes four stages: egg, larva, pupa, and adult. The larvae, or caterpillars, are the silk-producing stage. They feed on the leaves of various host plants, including species of Uapaca and Euphorbiaceae. The caterpillars spin cocoons made of silk, which are harvested for textile production.

Economic Importance

Borocera cajani is significant in the local economy of Madagascar due to its silk. The silk is harvested from the cocoons and is used to produce traditional Malagasy textiles, such as lamba and akotifahana. The silk industry provides income for many rural communities and is an important aspect of Malagasy culture.

Conservation

The habitat of Borocera cajani is threatened by deforestation and habitat loss. Conservation efforts are necessary to ensure the survival of this species and the sustainability of the silk industry. Initiatives include habitat restoration and sustainable harvesting practices.
