Zoological Society of London reveals breeding success for rare spider species

One of the world’s most endangered spider species has experienced a breeding success at the Zoological Society of London (ZSL).

Approximately 100 Desertas wolf spiders hatched on May 21, in what is only the second time the species has been successfully bred in captivity anywhere in the world.

The success follows two years of planning by zookeepers and conservationists at ZSL, who found a dark cellar in the zoo with the correct humidity and temperature for the spiders to breed.

Zookeeper Tyrone Capel said: “It has been fantastic to see these spiderlings hatch and, after two weeks clinging on to their mother’s back, climb off her to go their own way.

The large, grey spiders, native to the Desertas Grande island in Madeira, only breed once or twice in their lifetimes.
