Hawkmoths are Sphingidae and one of the most amazing insects to arrive at the purpose-built moth wall in REGUA’s garden at night. They are bulky and fly like nitro-fuelled rockets in what seems parabolas bashing themselves in the process coming to land under lamps. Lepidopterists say that they are guided by stars and perhaps they believe they have landed just by one of the billions out in the sky at night.
Curiously, wet evenings are best for the moth wall at REGUA, and it’s hard to see the stars at such times. These moths are important pollinating species for many tree species of the Atlantic Rainforest, but their preferences remain to be researched.
This is an example of Eumorpha labruscae and left Alan Martin author of REGUA publication, Guide to the Hawkmoths of Serra do Orgaos green with envy as he hasn’t seen it. Alan’s book says this is a widespread species and March was a good time to see it on the wall, so hopefully he will catch up with it on a future visit.
