On 1 August 2015, after the earlier flowers and bees of the botanical garden then, to the Victoria amazonica hothouse. This giant water lily species did not have a flower yet, but it did have a bud, as this photo shows.
But there were not only adults. This species reproduces here, so there were young ones on that tree as well, like this one.
This photo shows the smallest one of the new generation of giant prickly stick insects, while feeding.
