Oh gosh, thank you so much!! I was so excited to find your site last night, I spent like an hour scrolling through your 'Lepidoptera of 2022' page and fawning over the images you managed to capture! You're so lucky to find such beautiful specimen :,D! I can't wait to see more from you!! ( I think I deleted my comment by accident so I'm writing another, pardon if i'm being a fool, lol- )
Depending on the region they're in (in terms of seasonal temperature that allows them to have more/less breeding cycles in a given year), luna moths can have some slight color variation. The ones hatched closer to wintertime are a little "bluer" and they are more green the further you get into spring and summertime :0 IIRC, color is also a trait of their sexual dimorphism; males are typically a slightly lighter shade
