Adult dragonflies will eat any insect as long as they are able to catch it. While they usually eat mosquitoes and midges, they also eat butterflies, moths, beetles, bees, flies, and even other dragonflies. The general rule is that larger dragonflies will eat insects of body weight daily.
Origin of the name Viola: Derived from the Latin viola (a violet). The name has been in use since the Middle Ages but did not become common until the middle of the 19th century when the use of flower names came into vogue. From A World of Baby Names by Teresa Norman.
This unique viola is based upon a model commissioned by renowned British violist Lionel Tertis in the 1930s. Though it was not built by Tertis, the design is still credited largely to him.The original body length was 16.5, while this version has been scaled down to 15.25.
