Many birds glean for insects, invertebrates, fruit, or seeds. Some hunt insects by suddenly attacking from a branch. Some hunt insects by suddenly attacking from a branch. Those species that seek pest insects are considered beneficial 'biological control agents' and their presence encouraged in biological pest control programmes. [ 150 ]
Insects are taken exclusively by around 12 species, in great numbers by 44 additional species, and opportunistically by a great many others. [23] The diet of the honey-buzzards includes not only the adults and young of social insects such as wasps and bees, but the honey and combs from their nests. [34]
Insect cooking oil, insect butter and fatty alcohols can be made from such insects as the superworm (Zophobas morio). [199] Insect species including the black soldier fly or the housefly in their maggot forms, and beetle larvae such as mealworms , can be processed and used as feed for farmed animals including chicken, fish and pigs.

Birds are one of only four taxonomic groups to have evolved powered flight. A number of animals are capable of aerial locomotion, either by powered flight or by gliding. This trait has appeared by evolution many times, without any single common ancestor. Flight has evolved at least four times in separate animals: insects, pterosaurs, birds, and ...
Anting birds may pick up the insects in their bill and rub them on their bodies, or may simply lie in an area with a high density of the insects and perform dust bathing-like movements. Insects used for anting secrete chemical liquids such as formic acid, which can act as insecticides, miticides, fungicides and bactericides.
Lepidoptera (/ ˌ l ɛ p ɪ ˈ d ɒ p t ər ə / LEP-ih-DOP-tər-ə) or lepidopterans is an order of winged insects which includes butterflies and moths.About 180,000 species of the Lepidoptera have been described, representing 10% of the total described species of living organisms, [1] [2] making it the second largest insect order (behind Coleoptera) with 126 families [3] and 46 superfamilies ...
