“What is this bug?” is all this reader asks in his submission regarding the black and yellow, winged bug pictured below. We have to admit, we are no experts on insects, despite identifying a lot of insect larvae. Our speciality is worms and worm-like organisms (which includes larvae), but not fully-grown insects. Nonetheless, we will do our best to give some possible identifications of the creature in the photo. From the sleuthing we did, we think this could be a fruit fly or a wasp. Specifically, it looks most like a Bactrocera jarvisi, AKA Jarvis’ fruit fly.
