天蚕Rhodinia fugax的五龄幼虫的背面是浅黄色绿色，腹面是深绿色绿色，两种颜色之间有一条横向分界线。幼虫的形态发生了变化。fugax在颜色和形状上与寄主植物齿叶栎（Quercusserrata）的叶子非常相似。本文报道了红腹小蠹幼虫体壁的光谱反射率。fugax对应于Q.锯齿叶在幼虫体壁中，腹面的蓝胆蛋白（BPs）比背面的蓝胆蛋白多。光照强度影响幼虫着色。在光照条件下（1000勒克斯），幼虫的被被是绿色，而在黑暗条件下（10勒克斯），幼虫变成黄色。血淋巴中BP-I的含量也受光照强度的影响。BP-I及其蓝色发色团的量在光照条件下比在黑暗条件下高。相比之下，两种光强度之间的黄色发色团含量几乎没有差异。当幼虫保持在光下，在腹侧和背侧表面的角质层中的BP-I含量高于在黑暗条件下，并且其发色团含量与BP含量平行。而BP-II及其发色团在表皮中的含量不随光照强度的变化而变化。此外，珠被中黄色发色团的数量也不受光照强度的影响。因此，光刺激BP-I及其发色团在血淋巴和角质层中的积累，而BP-II及其发色团在表皮中的积累不受光强度的影响。这些结果表明，BPs和它们的发色团决定了幼虫的颜色，并可能在R.暂时性幼虫
The fifth instar larva of the saturniid silkworm, Rhodinia fugax, is light yellowish-green on its dorsal surface and dark green on the ventral surface with a lateral demarcation between the two colours. The larva of R. fugax closely resembles the leaves of the host plant, Quercus serrata, in colour and shape. The spectral reflectance of the larval integument of R. fugax corresponds to that of the Q. serrata leaf. In the larval integument, there is more blue biliproteins (BPs) on the ventral surface than on the dorsal surface. Light intensity influences larval colouration. The larval integuments are green under light conditions (1000 lux), whereas larvae kept in dark conditions (10 lux) turn yellow. The BP-I content of the haemolymph is also affected by light intensity. The quantities of BP-I and its blue chromophore are higher under light conditions than under dark conditions. In contrast, there is little difference in the yellow chromophore content between the two light intensities. When larvae are kept in the light, the BP-I content in the cuticle is higher than under dark conditions in both the ventral and dorsal surfaces, and its chromophore content parallels the BP content. However, the amounts of BP-II and its chromophore in the epidermis show no change with the light intensity. Moreover, the quantity of yellow chromophore in the integument is also not affected by light intensity. Therefore, light stimulates the accumulation of BP-I and its chromophore in the haemolymph and cuticle, whereas the accumulation of BP-II and its chromophore in the epidermis are not influenced by light intensity. These results suggest that BPs and their chromophores determine the larval colouration and may play an important role in the cryptic colouration of R. fugax larvae.
