Hyles dahlii
Hyles dahlii is a moth of the family Sphingidae first described by Carl Geyer in 1828. Distribution. It is found on Corsica, Sardinia and the Balearic Islands. On rare occasions it is found on Sicily and along the north-eastern coast of Spain. It was introduced to Tunisia in the mid 1980s. On Menorca, the "Hyles dahlii" population consists of a hybrid with "Hyles euphorbiae". Due to this hybridisation, only few characteristics of "Hyles dahlii" are present in the imago. There is also hybridisation on Malta. Here it is a hybrid between "Hyles dahlii" and "Hyles tithymali". Research  suggests that "Hyles dahlii" is in fact a species which evolved from "Hyles tithymali" through isolation. Description. The wingspan is 65–85 mm. Biology. Adults are on wing from May to June and from August to September in two generations. The larvae feed on various herbaceous plants, including "Euphorbia paralias", "Euphorbia myrsinites", "Euphorbia characias", "Euphorbia dendroides", "Euphorbia pithyusa", "Euphorbia pinea" and "Euphorbia terracina".
