Anisota oslari




the south of the USA (New Mexico, southeastern Arizona, southern Colorado, western Texas) south into Mexico (Sonora)


large for an Anisota, wingspan in between 4,5 (males) and 7 cm (females)


at least two flights annually (June/July and August). In captivity when too warm in autumn a third (partial) flight is possibly as late as mid October

Food plants:

Quercus, especially out of the white oaks and suber groups


Fairly easy and fast growing. Feeds in large groups, but older caterpillars should be given enough space.  Start in well ventilated plastic containers, but move to a netted cage  when the caterpillars become older. Watch out for condensation  and do not give wet leaves. Ready to pupate in four weeks. A living room temperature is enough (though on the warmer side as they are only available in the northern hemisphere summer). The pupal stage between summer generations is only a few weeks. Pupae after the last flight overwinter in a cool, frost free room. Adults do not emerge until (early) summer.
