Some outstanding photos by Chuen Man Chang in Brisbane, of a reasonably outstanding fly. I mean, it might not be up to the standarads of Lamprogaster corax, which I posted back at #1600, but it’s still up there.
L. bicolor is an East Coast species, found from the New South Wales Central Coast, up to the vicinity of Brisbane, Queensland. They’ve been observed to gather in small groups on tree trunks, where courtship and social display involves rowing the wings and extending and retracting the mouthparts - basically waving and blowing kisses.
