The moth members of this Order of insects include a large number of diverse families. Moth groups include micro moths, leaf miners, clothes moths, plume moths, ermine moths, burnets, geometrids, silk moths, sphinx moths, tiger moths, wasp moths, noctuids, underwings and many others.
It is interesting to ponder why moths that are primarily active during the night would employ such varied coloration. Judging from how this moth blends well with the underside of these fern fronds, this striking green Pyralid probably uses its coloration to conceal itself during the daylight hours by resting on green plant material. Notice how the edges of the wings are deckled and serrated, taking on a weathered and worn appearance that probably matches decaying leaf edges and helps to break up an observers recognition of a wing edge.
