About Drosophila picticornis
Drosophila picticornis breeds in fermenting sap flows, an important distinction from the decaying-bark substrates used by many other Hawaiian picture-wing flies.
Natural history and identification
Drosophila picticornis breeds in fermenting sap flows, an important distinction from the decaying-bark substrates used by many other Hawaiian picture-wing flies. Its Kauaʻi occurrence and placement within the picture-wing radiation are documented in the phylogenetic literature. A sap-flow breeding record describes the larval resource; it does not mean that the adult fly damages healthy trees or is equivalent to an introduced fruit-infesting pest.
Kauaʻi occurrence and evidence
Atlas occurrence category: Present. Wing-diversity database lists D. picticornis from Kauaʻi; current ITIS name remains valid.
Evidence limits
The cited observations describe the evidence currently available for this account. They do not establish a complete life history or a measured current Kauaʻi population trend.
