text_A: The reproductive stage of the insect is the winged adult or imago. The surface of both butterflies and moths is covered by scales, each of which is an outgrowth from a single epidermal cell. The head is small and dominated by the two large compound eyes. These are capable of distinguishing flower shapes or motion but cannot view distant objects clearly. Colour perception is good, especially in some species in the blue/violet range. While moths have antennae that taper or display a feathery structure, butterfly antennae have multiple segments and clubbed ends. The sensory receptors are concentrated in the tips and can detect odours. Taste receptors are located on the palps and on the feet. The mouthparts are adapted to sucking and the mandibles are usually reduced in size or absent. The first maxillae are elongated into a tubular proboscis which is curled up at rest and expanded when needed to feed. The first and second maxillae bear palps which function as sensory organs. Some species have a reduced proboscis or maxillary palps and do not feed as adults.
text_B: If a rainforest ecologist were to find a new species of brilliantly colored butterfly, and through various other methods was able to know with complete certainty that it was indeed a butterfly and not a moth, would the presence of feathery antennae be a game-changing discovery, perhaps representing some unforeseen evolutionary adaptation?
YES.
