We may not like every type of animal we see, but they all have their place in the scheme of things. I’m personally fond of things others may not be – just call me contrary.
Armenia (the snail parasite blowfly) is certainly colourful and presumably to be thanked by gardeners for helping keep snails under control. There are several species, and this one is likely to be A. imperialis, the yellow-headed snail parasite blowfly.
The Queensland Museum says:
Many blowflies attack invertebrates, such as insects and snails. The Snail Parasite Blowfly often rests on rocks and fallen wood. Females give birth to large, well-developed larvae that are thought to be parasites of land snails. Common in open and closed forest in eastern Queensland and New South Wales.
Length 10-15 mm. The bright yellow head contrast with the thorax and abdomen which are metallic green or bronze with silvery-white spots. The wings are clear with dark bases.
