Field Notes

Description:

Zygaenid moths are typically day-flying with a slow, fluttering flight, and with rather clubbed antennae. They contain hydrogen cyanide (HCN) throughout all stages of their lifecycle. Unlike most insects with such toxins, they obtain glucosides from feeding on birds-foot trefoil (Lotus) so they can use HCN as a defense. However, they are capable of making HCN themselves, and when in an environment poor in cyanide-producing plants, synthesize it themselves. - Wikipedia

Habitat:

Urban garden.

Notes:

(Zygaenidae; Procridinae)
* Endemic to the Philippines
