Features
Characteristics of the adult bees
The moths reach wingspans of 65 to 85 millimeters, and have the typical species of the genus Hyles coloring: your front wings are olive brown and wear a corrugated and indented weißlichgraue binding, which starts on wing trailing edge near the wing root as a broad strip and gradually narrowing to the Apex runs. The Saumfeld is colored as whitish. The hind wings have a broad middle, pink, red tie, a black base and a black Saumbinde. On the wing inner edge bordered by pink red band on a white spot. The coloring of animals is only slightly variable and is reminiscent of a dark-colored and heavily mottled copy of Hyles tithymali.
Features of the crawler
The caterpillars are similar to those of the spurge hawkmoth and have grown a dark gray color. Your body is covered with many fine whitish dots. The head capsule is usually purple, the orange Analhorn. On each body segment has two oval, white eye patch, which are entire - black border. Along the back runs a fine orange longitudinal line along the sides extend below the spiracles a white alternately red and yellow-colored longitudinal line. The ventral side of the caterpillar is yellowish.

Occurrence
The animals are found in Corsica, Sardinia and the Balearic Islands. Occasionally, one can also prove the nature in Sicily, very rarely, on the north east coast of Spain or on the coast of Tuscany. In Tunisia, the species was exposed in the mid- 1980s.
In Minorca the original population of Hyles dahlii is so strong hybridized with spurge enthusiasts that few characteristic features of Hyles dahlii can be observed in the Imagines. A similar hybridization of the kind happened in Malta with Hyles tithymali. There is evidence that Hyles dahlii developed by isolation of Hyles tithymali as an independent species.
Hyles dahlii colonized rocky mountain slopes with vegetation of pines and bushes.
Flight times and caterpillars
The moths fly in two generations from May to June and from August to September. In warm years, a partial third generation may occur. The caterpillars are found from June to October.
Food of the caterpillars
The caterpillars feed on herbaceous spurge species ( Euphorbia ), especially beach spurge (Euphorbia paralias ), rolling - spurge ( Euphorbia myrsinites ), palisades spurge (Euphorbia characias ), Tree - spurge ( Euphorbia dendroides ), Euphorbia pityusa, Euphorbia pinea and Euphorbia terracina.
Development
The eggs of the species resemble those of the spurge hawkmoth, are nearly spherical and colored light blue green glossy. The caterpillars after hatching three to four millimeters long and cream-colored. The dolls look where the spurge hawkmoth very similar. They are the overwintering stage of Art Known parasitoids are the tachinid Exorista larvarum and Masicera sphingivora.
