Notes from Kaziranga: Pentatomid bug eggs

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.

    @Laks: beautiful. I find the surface structure incredible. It’s developmental biology before the real development has even begun ? What layer/cells from the garnered form egg cases? Also those pores truly through holes or covered by a membrane? What about bacterial protection?

    Incredible video.

    Dear Rajesh (Laks)

    Good to note that you were able to experiment with the foldscope during your hectic trip to India..Lovely capture of bug egg..did you check the nymph close up?

    @Bhanu (Akka), you wont believe what happened when I tried imaging one such larva. It should have made a good sample for viewing, but It sprayed something all over the slide like a spittlebug does. It has some really interesting bubbling. I didnt get the time to pick another one. I hope you image some bugs through the foldscope since you are a great expert on them. See video below
