Drosophyllum lusitanicum

Overview

Drosophyllum lusitanicum forms dense rosettes of linear leaves covered in stalked, mucilage-producing glands. Unlike many bog carnivores, it grows in dry Mediterranean heathlands. Its large yellow flowers have five petals and are carried above the leaf traps.

Bertol and colleagues compared living plants with plant-shaped artificial traps coated in odourless glue. Living leaves caught more insects, especially small flies. Scent or visual attraction was proposed, but the experiment did not isolate one universal lure compound.

Salces-Castellano and colleagues found that removing flowers did not reduce prey capture in their experiment. Hand-pollination and access by insect visitors increased seed production compared with untouched bagged flowers capable only of spontaneous selfing. Thus successful self-pollination does not make floral visitors irrelevant, nor does a conspicuous flower automatically act as a prey lure.
