Find a proliferating marker in Drosophila

[=?big5?q?thosten-1?=]

I want to observe morphogenesis furrow in eye disc. 
Cyclines were the downstream of my system. I need another marker to label G2, M or G1 phase. In human celline, ki-67 or PCNA are good ones.
Is there any specific protein I can label in drosophila eye-disc?
Think you for any suggestion.
