Heterorhina elegans and Protaetia aurichalcea
On this tree trunk, a glistening green Heterorhina elegans and a mottled Protaetia aurichalcea—both flower chafers—share sap with a few hungry ants. The oozing resin serves as a natural feeding station, drawing together beetles and ants alike in a moment that highlights how even a single drop of sap can sustain a tiny ecosystem.

"Heterorhina elegans" is a species of Scarab beetle found in India and Sri Lanka that belongs to the flower chafer subfamily. Its genus name is frequently misspelled as ""Heterorrhina"". The adults are about 2 to 3 cm long and are usually bright glassy green appearing reddish at some angles.
