The species is possibly Podagricomela nigricollis but we are still waiting them to pupate and to emerge. Should be easily identified since the two mining Podagricomela adults are very different.
Why not Phyllocnistis citrella, the leafmining moth? The frass are dark color and there are many holes near the mines. The holes are typical feeding harm by beetles. The larva can move out and make a new mine in the same leaf or in a different leaf.
虫道粪便较黑，且周围有甲虫成虫取食的小孔，并且幼虫可以爬出虫道重新潜食，甚至转叶为害。明显与柑橘潜叶蛾为害状不同，初步判定为柑橘潜叶甲。目前正在饲养等待化蛹羽化，做最后的鉴定。
You can campare the above mines with those of Phyllocnistis citrella. 请对比它们与柑橘潜叶蛾虫道的区别。
