Animal Encyclopedia: Spider bat fly

Basilia falcozi

FAMILY

Nycteribiidae

TAXONOMY

Nycteribia falcozi Musgrave, 1925, Australia.

OTHER COMMON NAMES

None known.

PHYSICAL CHARACTERISTICS

Adults lack wings and their body is compressed dorsoventrally, so that head and legs arise from the dorsal surface of the thorax,

giving them a spiderlike appearance. They have long legs with strong claws. The pupae are shining black and flattened.

DISTRIBUTION

Australia.

HABITAT

Ectoparasites on cave-dwelling bats of the family Vespertilionidae.

BEHAVIOR

Adults stay on host except to deposit pupae in roost.

FEEDING ECOLOGY AND DIET

Hematophagous.

REPRODUCTIVE BIOLOGY

Females deposit fully developed pupae singly, gluing them to vertical substrata (e.g., cave walls and trees) in the vicinity of the host bat roosts. This process may be repeated several times during the female's lifetime. Emergence of the adult is triggered by the warmth or contact of a roosting bat.

CONSERVATION STATUS

Not threatened.

SIGNIFICANCE TO HUMANS

None known.
