Host plants:
According to literature, the larvae have been recorded on Arbutus unedo and Laurus nobilis. I found them on Quercus coccifera in the Spanish Monegros, so that it is quite probable that the species uses a broader variety of surely always evergreen groves.
Habitat:
Hoyosia codeti inhabits warm evergreen woodlands and grove-rich, semi-open habitats both in dry and more humid environments.
Life cycle:
The larva hibernates and develops from late summer/autumn to spring. The development is probably only interrupted by frosty periods or in cooler regions by a dormancy. I recorded mature larvae in a small, dry and hot Quercus coccifera shrub in the Monegros (Zaragoza) in mid-May 2022. The larvae created their cocoon a few days later in the litter or on branches. The moths appeared three months later in September. In literature, there are already records of adults from June. But most cocoons should give the moths only after the peak of the summer heat and drought in August/September. The resulting larvae have to cope with hard leaves, but no more with extreme heat and drought then.
Remarks:
Hoyosia codeti occurs in N-Africa and SW-Europe (Iberian Peninsula, S-France).
