Eilema Caniola

''Eilema caniola'', the hoary footman, is a moth of the family Erebidae. The species was first described by Jacob Hübner in 1808.

Subspecies

*''Eilema caniola caniola''
*''Eilema caniola torstenii'' von Mentzer, 1980 (Spain)

Distribution and habitat

This species can be found in North Africa, in western and southern Europe, in eastern Europe up to south-western Russia, in the Near East, in the eastern Palearctic realm, and in the Oriental realm. These thermophilic moths usually occur in urban areas and as a caterpillar on old walls, roofs, shingle beaches, and rocky areas.

Technical description and variation

The wingspan is 28–35 mm. It is almost the same in colouring as '' Eilema griseola'' and '' Eilema lurideola'' but the forewings are much smaller, the outer margin is oblique, only slightly excurved; the colour is much lighter, more yellowish grey, so that the pale yellow costal stripe is less prominent. Hindwings are very pale, scarcely darker at the costal margin, with the apex much more pointed than in the two species mentioned, with which it might be confounded.

It is at once distinguished from '' Eilema complanum'' by the underside of the forewing, on which the pale grey colour extends to the margin, the latter not being broadly yellow as in ''E. complanum''. - ab. ''vitellina'' Bdv. is a form with the forewing dusted with grey close to the distal margin and of a pale bright yellow ground colour in the male - ab. ''albeola'' Hbn. is considerably smaller, and, except for the bright yellow thorax, entirely white on the upperside; it occurs among ordinary specimens.

Larvae are grey or reddish brown with dark dorsal line, red subdorsal lines edged with black and occasionally spotted with white or black.

Biology

These moths are nocturnal and rest at day on shady rocks. They fly in two or three generations from July to September depending on the location. They are attracted to light. The larvae mainly feed on algae, especially on green films of ''Pleurococcus'' and on a variety of lichens growing on rocks, but also on the flowers of broom (''Genista'' sp.), birdsfoot trefoil ('' Lotus'' sp.) and clover (''Trifolium'' sp.).''Memim Encyclopedia''
