Hello, new poster here! So, I am planning on getting a tattoo of all 3 major dynastes tityus life stages on my calf (grub, pupa, beetle). However, I can't find seem to find any growth charts that state their size in mm in the pupa stage, to give as a reference to the artist... would anyone happen to have measured yours, or have a good photo of one next to an adult beetle? Thanks so much!
