This is a bit tangential, but my Ph.D. thesis work was with a group of insect development and physiologists studying diapause in Aulocara ellioti, the Big Headed Grasshopper, whose diet is almost exclusively western wheat grass. Eggs are laid in ground in late summer. Development proceeds to a point, then stops. The next spring, development continues as the nymph breaks a membrane and consumes what is analogous to the yolk in a bird's egg.
The degree of provisioning of the egg (e.g., big eggs) was an important factor in the survival and vigor of the resultant nymph. It also seemed to be part of what was, at the time, termed maternal influence. I suspect these days it might be termed epigenetics. Unfortunately, the lead scientist, who was still with us a couple of years ago, has dementia, so I can't ask her.
