Answer to this issue’s ARIZON-WHA?! Photo challenge:
If you guessed beetle grub, congratulations! Since it’s a white grub, we can identify this big chunk as belonging to the scarab beetle family, Scarabaeidae. Due to its size and the location where it was found, it’s pretty likely that this one is a baby Western Hercules Beetle, Dynastes grantii. Larvae of this species can spend 2-3 years as a crazy-looking underground monster like our friend up above, but once they’ve developed into adults they only live for 2-4 months. As grubs, they eat decaying plant material (that makes them decomposers, y’all!) but as adults they feed on tree sap by making a small wound in the tree (this doesn’t hurt the tree). I’ll give you a dollar if you eat it.
