我们推测蝴蝶的多不饱和脂肪酸可能来自食物，并且在变态期间可能有大量的身体脂肪损失。为了证实这些假设，我们分析了饮食，幼虫和蝴蝶Morphopeleides的脂肪酸组成和含量。幼虫和蝴蝶的食物和组织都含有高浓度的多不饱和脂肪酸。日粮中亚麻酸占总脂肪酸的19%，亚油酸占8%。在幼虫中，近60%的总脂肪酸是多不饱和脂肪酸：亚麻酸占总脂肪酸的42%，亚油酸占17%。在蝴蝶中，亚麻酸占36%，亚油酸占总脂肪酸的11%。幼虫的总脂肪酸含量比蝴蝶高得多（20.2比6.9毫克）。我们的数据表明，从幼虫到蝴蝶在变态过程中的转化大大降低了总脂肪酸含量。多不饱和脂肪酸在幼虫和蝴蝶的食物中有生物增强作用。这种膜的多不饱和度在提供飞行中有用的膜流动性方面可能具有功能重要性。
We hypothesized that the polyunsaturated fatty acids of the butterfly were probably derived from the diet and that there might be a great loss of body fat during metamorphosis. To substantiate these hypotheses, we analyzed the fatty acid composition and content of the diet, the larva, and the butterfly Morpho peleides. Both the diet and the tissues of the larva and butterfly had a high concentration of polyunsaturated fatty acids. In the diet, linolenic acid accounted for 19% and linoleic acid for 8% of total fatty acids. In the larva, almost 60% of the total fatty acids were polyunsaturated: linolenic acid predominated at 42% of total fatty acids, and linoleic acid was at 17%. In the butterfly, linolenic acid represented 36% and linoleic acid represented 11% of total fatty acids. The larva had a much higher total fatty acid content than the butterfly (20.2 vs. 6.9 mg). Our data indicate that the transformation from larva to butterfly during metamorphosis drastically decreased the total fatty acid content. There was bioenhancement of polyunsaturated fatty acids from the diet to the larva and butterfly. This polyunsaturation of membranes may have functional importance in providing membrane fluidity useful in flight.
