Genome Length:

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.
