Insect of the order Trichoptera. Adults are generally dull brown, mothlike, with wings covered in tiny hairs. Mouthparts are poorly developed, and many caddis flies do not feed as adults. They are usually found near water.

The larvae are aquatic, and many live in cases, open at both ends, which they make out of sand or plant remains. Some species make silk nets among aquatic vegetation to help trap food.

The flag uses the pan-Arab colours. The design may have been inspired by the pre-1958 Iraqi flag. Effective date: 24 November 1961. >>
