Nice find!
The larva in the picture look a lot like the sugarcane beetle larvae that I raised 2 years ago.
Thanks, that may confirm what I suspected because we get alot of those. They are a fun beetle and my daughter's first insect love.
I like how they stridulate when they are disturbed, and I can't help but save them from Big headed ants, when they are under attack they stridulate like crazy.
My daughter started out by finding Sugarcane beetles and Scarlet millipedes on our porch when she was around 18 months old. I found her picking them up and trying to kiss them!
Not knowing much about arthropods, I looked the creatures up online to see if they could harm her and developed an interest myself. We kept the beetles, pedes, and
Pycnoscelus surinamensis in a container with the soil we found them in when they weren't walking about on our porch, and fed them fruits and veggies.
She will be 6 this month and now we keep many various arthropods.
I have since taught my daughter that bugs don't like kisses.
