I found some ova in cold storage that I forgot I collected last year! Egg rings, on scrub oak, from the buck moth (Hemileuca maia) collected in September of 2017 and likely due to hatch later this month. And walkingstick (Diapheromera femorata) ova from a female feeding on black walnut. Not sure when they should hatch but it should be soon!
both look like plant seeds. i wonder whether this is a kind of camouflage.
A dumb question for an expert: Do most insects start in the ova stage?
