I got 6 pachliopta kotzebuea and 6 morpho helenor the pachliopta are 2 weeks old so already 2 died (morpho can live up to 2 months) and I've an ethic question : this is the last 2 days with sunny and warm weather should I let them fly outside and certainly die quickly but free or keeping them? it's 23 degrees outside but only 15 at night so they might die this night
