Answer:
You both win! Different butterflies actually have different numbers of chromosomes! The Polyommatus atlantica butterfly of the Lycaenidae family has 446 chromosomes. On the other hand, the Hypothyris thea butterfly of the Nymphalidae family has only 10 chromosomes. Others like the Squinting Bush Brown butterfly (Bicyclus anynana) has 28 chromosomes and the Red Postman butterfly (Heliconius erato) has 21 chromosomes.
Thanks!
