Group:

Insect

Estimated genome size:

Its body is about 16-21 mm, and its probiscis (tongue) is 20-47mm long.

Size:

Its body is about 16-21 mm, and its probiscis (tongue) is 20-47mm long.

Distribution:

Its range is in south western Africa, specifically extreme southwestern Namibia through the western part of Northern Cape Province in South Africa (Namaqualand), and into the northwestern portion of the Western Cape Province. Key areas of high diversity include the Kamieskroon area of Namaqualand and the Pakhuis Mountains in the Western Cape.

0.56 Gigabases

BUSCO completeness score (single and duplicated genes):

99.0% [S: 94.7%, D: 4.2%]

Importance:

The Long-tongued fly is important ecologically. It is a keystone pollinator for a whole guild of long-tubed, vividly colored flowers. Through its specialized morphology and behavior, it facilitates efficient and species-specific pollination, supports plant biodiversity, and likely drives co-evolution in its plant partners.

Species Card Details

Importance:

The brightly coloured red flowers produce an abundance of black nectar that attracts sunbirds, Cape white eyes, bees and butterflies. Leaf and stem extractions are used to treat septic wounds, sores, bruises, backache and rheumatic joints. It is a traditional remedy for snakebite.
