Other Common Names
I saw a lot of Grass Yellows during my second trip to Cairns in April 2006. In certain areas they were very common, and there were plenty of them flying even on overcast days, and in fact even when fairly heavy rain was falling.
It's unlikely that all the specimens I saw were all of this species, as there are 6 species of Grass Yellows in the Cairns area. Unfortunately they never land with their wings open, so telling which butterfly is which species is difficult without catching them. I think on my next trip to Cairns I might have to take a net.......
