Geometer Moth

Geometridae; Sterrhinae; Scopulini, Scopula sp. This Scopula sp. is a Geometer Moth (sometimes called a Wave because of the wavy patterns on the wings). When I spotted it, I could see that it was in perfect condition and was wondering if it had just emerged from its cocoon. While I was focusing my camera, it gave me the answer, by excreting the orange/brown liquid that you can see, on the leaf. So, I knew that it had emerged in the last hour or two and had not yet taken to the air. When a moth emerges from its cocoon, it has to find a comfortable position (usually on the stem of a plant) with its head up and its wings hanging down. It adopts this position because its wings are soft and floppy. Over the next hour or so, the wings are pumped full of Haemolymph (arthropod blood) and gradually expand and stiffen. When the moth feels that it is ready to fly, it discharges the liquid (left over from the metamorphosis in the cocoon). The liquid is called Meconium (metabolic poop) and discharging it lightens the weight of the moth. So, knowing that it was about to attempt its first flight, I did not take any more photos and quietly backed off, to leave it in peace.
