I was walking around our guest house in Kaziranga when under a fern pinna (leaflet) I noticed a cluster of eggs and some newly hatched larva. The Larvae looked like the first instar of a pentatomid bug. The eggs were all stuck together and to the pinna and had a hard shell (chorion).
Below is a movie of the bug eggs under the foldscope. The eggs had both grooves and pores. These pores called aeropyles are important for gas-exchange. In some views, each aeropyles seemed to be surrounded by grooves. I found this arrangement really aesthetic. I think it is time to make a series on insect egg surfaces. I am sure they vary greatly between different types. Perhaps those in warmer climes are better placed to get started on this.
