Coloured scanning electron micrograph (SEM) of Grass bagworm moth (Brachycyttarus griseus). The compound eye is composed of numerous facets (ommatidia), each of which contains a surface lens. Beneath each lens are retinal cells, which send nerve signals to the optic nerve. The ommatidia are often hexagonal in shape and are tightly arranged to form a large compound eye. Compound eyes allow for the detection of small movements but are weak in distinguishing fine details. Wikipedia reference: The Grass Bagworm (Brachycyttarus griseus) is a moth of the Psychidae family. It is native to south-east Asia, including Vietnam, Malaysia, Sabah and the Philippines, but has been introduced in Guam and Hawaii. It is abundant in lawns, but is not considered to be a significant pest. Larvae can feed on various ornamental plants such as Canna lilies and Anthuriums, creating large holes in the leaves.
