Tegula
As Tegula (which, Pl. Tegulae) is referred to in butterflies , Hymenoptera and Diptera paired on the second thoracic segment ( Mesothorax appendages located). In stone flies and earwigs , they can be on the second or third segment (meso- or metathorax ). When beetles no tegulae are formed. The tegulae are mobile and act as cover scales for the sensitive wing base. They are elongated to triangular in shape and often have thick hairs on the top.
The attachment point is closed with a thin membrane, the location of which can be used to distinguish between butterflies and moths , for example . In the butterflies it is always at the lower edge, in the night butterflies (including the Hesperiidae ) around the middle (see fig.). In larger moths such as the swarms (Sphingidae), the tegulae take up about the outer third of the thorax when viewed from above. In some species, such as Hyles lineata and Hyles livornica , the shape and color of the tegula scaling can help to differentiate between species.
