Diagnosis. Nominotypical caniola is characterized by pale wings, often ash grey with a fine silky sheen and a weakly expressed ochreous costal stripe. Vertex and forehead yellow or light orange; hindwings light whitish grey or ochre-grey; underside of the forewings of males without androconia, underside dorsally with a weak greyish diffusion.

Identification of Eilema caniola caniola on external morphology is not always easy and this species can often be confused with other species of Eilema sensu lato, but it is easily identifiable from the genitalia.

Re-description: Imago ( Figs. 1–2 View FIGURES 1–8 ). Average wingspan males 32.4 mm (n=10; 26–36 mm); average wingspan female 29.7 mm (n=10; 25–32 mm).

Genitalia ( Fig. 49 View FIGURE 49 ). Male and female genitalia: taking into account that Eilema is a monotypic genus, the description that has already been given for the genus holds as valid.

Immature stages ( Fig. 75 View FIGURE 75 ). The last instar larva has an average length of 21 mm. Cephalic capsule dark brown, with a smooth vertex. Setae very short with verrucae D1 and D2 dark, SD 1 dark grey and L2 and L3 orange or yellow; dorsal line wide and dark, bordered by a narrow whitish to light grey line. Between D2 and SD 1, a band with grey and black spots, mixed with orange and yellow. Pupa light brown, smooth, somewhat translucent, stylized and glabrous; clypeus short, tip of abdomen rounded, without cremaster. In pupa of male, the antennae and proboscis reach the tip of the wings, and are shorter in females. The very light silken cocoon is woven in any corner.

Molecular data

The samples of Eilema caniola caniola collected in the mainland form a compact group within this species’ clade, (within-group TN-dist=0.22%, n=7), while the samples from the Balearic Islands corresponding to subspecies torstenii are slightly separate from such cluster.

Biology. Bivoltine or even trivoltine species, continuously on the wing from May to October, even until November in some southern locations. It inhabits all types of environments, although it seems to favour those with xerothermic characteristics, at altitudes from sea level to about 1800 m. The imagos are nocturnal, and both males and females come to artificial light. Larvae feed on lichens, but they may also eat leaves and flowers of various Fabaceae ( Genista , Lotus , Trifolium , and Anthyllis ) ( Ylla et al. 2010). In captivity the larvae can thrive with artificial diet.

Distribution ( Fig. 95 View FIGURES 95–109 ). Holomediterranean. Present in northern Africa, western, central and southern Europe and Asia Minor, and also in the large Mediterranean islands. It occurs throughout the Iberian Peninsula.

Observations. We consider that the taxon Eilema caniola gibrati (Oberthür, 1980) does not differ from nominotypical caniola either in internal and external morphology or in genetic traits.
