Zygaena favonia is a species of moth in the Zygaenidae family.[1] It is found in the Atlas Mountains, (Morocco, Algeria, Tunisia).In Seitz it is described Z. favonia Frr. (= sarpedon Hbn., cedri Bruand) (4g). This form belongs to a group of North African Burnets the pattern of the forewings of which reminds one much of the preceding species [''[[Zygaena sarpedon]], while the abdomen is red from the middle nearly to the tip, which gives the insect a characteristic aspect and renders it easy to recognize even when it flies quickly past. The whole of Mauretania, everywhere common — ab. vitrina Stgr. (4g) [now ''Z. favonia'' ssp. ''valentini'' Bruand, 1846], which I found only at very limited localities, for instance near Constantine and at the cemetery-wall near Batna (Prov. of Constantine), is easily differentiated by the transparent wings. -ab. staudingeri Aust. (4f) [now Z favonia Freyer, 1844] is similar, but has only a narrow abdominal belt, so that one might mistake the for a small loyselis, if it did not lack the red collar of the latter. — The insect described by Bruand as valentini [now ''Z. favonia'' ssp. ''valentini'' Bruand, 1846], in which the red spots are enlarged, may possibly belong to an analogous favonia-form. — The finest form of this group is thevestis Stgr. [now Z. ''favonia'' ssp. ''thevestis'' Staudinger, 1887 (4f), in which there is a large lobate subapical patch. — All these varieties occur all over [[Mauretania]], on hills, in dry beds of rivulets, and on waste ground. The commonest form is favonia, which is found in June on nearly all the thistles growing at the road-sides and in the fields. The females have an extraordinarily thick body, and apparently scarcely take to the wing before copulation.[2]
