Liquidamber, Arbutus unedo, Rhus thypina(?),
Arctostaphylos
They like hot and dry condition. The species is not easy to
rear. They prefer Arbutus unedo. Cocoons can be kept at
10-13 C and dry conditions. After getting out of cold
storage, they emerge within 9 days. Pairing is not always
easy, but could be achieved by hand pairing. Females lay
around 60-80 eggs. They usually lay all their eggs within
two days. The eggs take about 3 weeks to hatch at room
temperature and larvae do best sleeved in full  sun. Larvae
complete development in about a month if temps are
warm.  They  do not do well in humid crowded conditions. 
There is only one brood per year that  normally flies in
March-April but it depends a bit on the weather.  Both
males and  females are diurnal and mating is very quick
sometimes lasting only a few minutes.   Females are not all
that fecund either laying around 60-80 eggs on average
but some of  the larger females can lay a few more. When
the food is watered, they die easier.
