多泡体和板层体是节肢动物感光细胞特有的细胞器，在蚊子眼中的形成依赖于光。这些细胞器几乎不存在于光剥夺的眼睛中;当这种眼睛第一次被照亮时，它们大量形成。多泡体在横纹肌附近形成，然后向近端移动进入细胞体，最终转化为板层体和可能的致密体。将铁蛋白注射到头部血淋巴中的实验证实了横纹肌的包被小泡是胞饮小泡的假设。铁蛋白被横纹体囊泡吸收到细胞中，被多泡体隔离。
The formation of multivesicular and lamellar bodies, organelles characteristic of arthropod photoreceptor cells, is shown in the mosquito eye to be dependent upon light. The organelles are nearly absent from light deprived eyes; they form in large numbers when such eyes are first illuminated. Multivesicular bodies form adjacent to the rhabdomere, then move proximally into the body of the cell, ultimately being transformed into lamellar and probably dense bodies. Experiments in which ferritin was injected into the hemolymph of the head confirmed the hypothesis that the coated vesicles of the rhabdomere are pinocytotic vesicles. Ferritin taken into the cell by rhabdomeric vesicles is sequestered in multivesicular bodies.
