Fregate Island Palm Beetle

IUCN Red List: Vulnerable
EEP (EAZA Ex-situ Programme)

Fregate Island Palm Beetle is a large, flightless tenebrionid beetle, endemic to Fregate Island (Seychelles). In 1996 the species was rated as Critically Endangered since Brown Rats that were introduced into the island posed a threat. A captive breeding programme was established at the Zoological Society of London to prevent the species from becoming extinct. After an effective rat eradication programme was put in place, Fregate Island was declared rat-free in 2001. A new threat appeared in 2002 when a fungal infection affected most of the Narra trees (Pterocarpus indicus), an important species for Fregate Island Palm Beetle. A habitat restoration project allowed to increase the island’s forest diversity, enabling the beetle to use other plant species.
