Because beetle elytra may be common fossils in Pleistocene deposits, they are often important sources of data on Pleistocene environments. |
|
The body fossil record of arthropods in the Chinle Formation is limited to beetle elytra and a few poorly preserved wings of orthopteran insects. |
|
No detailed description of the insect could be found, but adults are dark brown with conspicuous yellows spots on the elytra. |
|
Other North American species have more distinct spots or bands on the elytra. |
|
Neither fly, and their hard outer wing cases, or elytra, have rows of small round pits in them. |
|
These insects have a hardening of the forewings to form an elytra which protects the hind wings as well as the abdomen. |
|
The elytra are of a miniatous red, striated and punctured, towards the apex rounded and serrated with two very minute approximate dentations at the sutural angles. |
|
The evolution of elytra may have been associated with the habit of living under the bark of trees, where protection for flying wings is required. |
|
The front pair, which may be thickened, leathery, or hard and brittle, are called elytra and usually serve only as protective covers. |
|
At rest, the fragile hind wings are hidden beneath the protective sheath of the hardened forewings, or elytra. |
|
The upper side of the elytra is pale, marked by fine parallel lines and moderately densely clothed with smooth hairs. |
|
When the beetle takes flight, the elytra open to allow the hind wings to propel the beetle through the air. |
|
By using electron microscopy, it was shown that strial pits on the elytra of I. pini carry spores like those of O. ips, yeast and other fungi. |
|
The unique elytra may well be the reason for the beetles success. |
|
Ghost Tiger Beetles are pale in colour, with faint brownish markings on the elytra, making it difficult to see against the sand. |
|
Mesepimera pubescent towards elytra, distinctly less so towards procoxal cavity. |
|
The female characters may be assumed on the head, afterwards on the thorax, and finally on the elytra. |
|
Some examples are very dark in colour, and then the pale neurations on the elytra become almost obsolete. |
|
Coleopteran pests: an insect of the order Coleoptera with four wings, the outer pair of which is modified into stiff elytra to protect the inner pair when at rest. |
|
Among the cerambycids, sound is produced either by rubbing the rear margin of the prothorax over a grooved area on the mesothorax or by rubbing the femurs of the hind legs against the margins of the elytra. |
|
|
The base of the elytra does not have a granular structure. |
|
The beetle is black with several white hair spots on the elytra. |
|
The male has the elytra narrowed distally. |
|
Elytra are a pair of hard forewings which protect the hind wings and the body of the beetle. |
|
Elytra black, glabrous, but only on posterior half with a sutural stripe of white hairs. |
|
Elytra piceous, gradually shaded into a castaneous margin, irregularly and minutely punctured, covered with ochraceous pubescence. |
