Synonyms, misspellings, wrong determinations, etc.: Tinea exiguella [Denis & Schiffermüller], 1775: 143, no. 21 Remarks: The identity of T. exiguella is very uncertain. The original description reads "Düsterer Sch[metterling] mit weißlichtem Querstriche", foodnote: "**Mit gespitzten Oberflügeln. (Alis cuspidatis.)", which is clearly different from the description of T. fibulella on the same page: "Purpurschielender Sch[metterling] mit 1. goldenem Gemeinmackel". Nevertheless, C. fibulella may be fuscous with a nearly white, but always incomplete cross fascia. |

Distribution:
|
Following Karsholt & Nieukerken (2010), the species is distributed throughout Europe, except for Portugal, Ireland, Iceland, large parts of the Balkans and the large Mediterranean islands. The first record for Serbia has been published by Kurz & Horvat (2010). The species seems to be absent from Asia, since there are no records from Siberia (Dubatolov 2009) or Japan (anonymous 2009a). The vertical distribution has been recorded from near sea level to about 1800 m a.sl. (Kurz & Kurz 2010).

The species inhabits diversified edges and clearings of woods, which are rich in grasses and herbs and include the foodplant of the larvae, Veronica chamaedrys. The imagines are frequently sucking on this plant too. They are day-active and mostly gregarious. The imagines fly in one generation per year from May to July, depending on the altitude (Kurz & Kurz 2010).

C. fibulella is quite similar to Cauchas leucocerella (Scopoli, 1763) when comparing the forewing patterns. In C. leucocerella, the incomplete median fascia is mostly better developed and more contrasting. Somewhat distally of the fascia, a distinct, yellowish-white costal spot is normally present. A light, indistinct, subbasal spot, often developed in C. fibulella, is usually missing in C. leucocerella. The vestiture of hair-like scales on the head is black in both sexes of C. fibulella, whereas in C. leucocerella it is conspiciously orange in the and mixed blackish and yellowish-orange in the . The hindwings of C. leucocerella are distinctly lightened towards the base, whereas in C. fibulella, they are of uniform colour. |
