Not a true species, but more a complex hybrid occurring only on Malta (a mix between H. euphorbiae, H. tithymali and a 3rd Hyles that is absorbed into the sammuti hybrid and no longer exists as species (referred to as H. melitensis)).
In between 6 and 7,5 centimeter
continuously when kept warm and not too dry
Euphorbia, including Euphorbia characias and myrsinitis
Easy and suitable for newcomers. Keep warm, dry and clean. Early instars in well ventilated plastic containers, older caterpillars in a netted cage. Place the cage in front of a south facing window. Fast growing and ready to pupate within 4 weeks. The pupal stage is short (usually less then 3 weeks, but depending on temperature and humidity). Best considered as a continuously brooding species. Do not attempt to diapause.
no Euphorbia = no caterpillars
