Green & greener.
A green bottle fly on a beauty berry leaf at Frenchman's Forest Natural area.
These are also know as a blow flies, blue bottle flies and carrion flies.. They are aggressive scavengers that very quickly arrive at the scene of freshly dead things and lay eggs that rapidly develop into voracious larvae. Various blow fly species do carry disease or are parasites but they are also important scavengers, pollinators, very useful in forensic entomology (remember Gil Grissom on CSI) and are used in maggot therapy (don't ask). The fly above was off duty and just frolicking in the morning sun :)
