Inca clathratus

Inca clathratus is a species of flower chafer in the family Scarabaeidae, indigenous to Central and South America.[1] These beetles can be seen surrounding the sap flows from injured or diseased trees anytime in the day and sometimes at night. They mostly feed at the sap flows of the trees, including avocado and mango trees. Like other beetles they also feed off of rotting fruit. There are a few different subspecies of Inca clathratus including: Inca clathratus sommeri, Inca clathratus clathratus, and Inca clathratus quesneli.[1] The species name has been frequently misspelled as "clathrata"[2] but the genus name Inca is masculine.[1]
