It seems to be the season for these clearwing tussock moths. The colourful caterpillars spin a loose net of silk on the folds of a broad leaf blade on or near their host plant. Suspended in the middle of the mesh, they turn into squirming chrysalides. Eclosion occurs with remarkable speed; in less than a week, the adults emerge, clinging to the hollow shell of their youth to rest from their exertion and mull their last meal. For they can feed no longer, having stored up enough food to transform themselves into winged bundles of sexual energy with feathery antennae that captures the aroma of distant ardour. After a while, they stir and ignite their thoracic muscles to scatter the powder that coats their tented wings and reveal a discal surface of glassy clarity save the fine costa of tracheal support. Settling on bark and branch, the moths hunch over to hide their orange heads and vanish amidst lichen and mould as invisible silhouettes that await a night of swift flight and frantic couplings.
