Large Grass-yellow possibly newly hatched
It is difficult to tell this butterfly from the other Grass-yellows in flight although it is slightly larger. Even with a photograph identification is not easy.
It's bright yellow colour is a joy to see as it flies slowly around the property close to the ground.
The dry season form is paler in colour and has more prominent markings on the underside.

Thought to be a Large Grass-yellow egg on Breynia 5th May 2016
On 5th May, 2016, we found tiny eggs that had been laid on new Breynia leaves. Six days later we discovered they had hatched overnight. The two larvae were so small we could only see them with a strong magnifying glass. The photograph below shows one of the larva after 24 hours since starting to eat. It measured 1.5 - 2 mm.
