Why do the larva grow larger and heavier when one parent is present, even though both parents help with feeding by bringing a food source to the larva before they hatch?

The correct answer should help explain why having one parent present present is better for the larva’s growth than having two parents. Perhaps, for example, having two parents takes away from the amount of food available to the larva, or causes some kind of biological reaction in the larva that inhibits their growth. Or perhaps there’s something about having one parent present that leads larva to eat more.

This makes the discrepancy harder to explain, because it’s something positive about having two parents present compared to only one.

If both parents use the carcass for their own food, that leave less food available for the larva when both parents are present compared to when only one is present. That could explain why the larva grow larger with only one present.

This doesn’t tell us why having both parents present would lead to less food for the larva. If anything, it suggests having both present would help the larva feed, which makes the discrepancy harder to explain.

But why would having two parents around be worse for larva growth than having only one present? This doesn’t differentiate between having both parents around compared to only one.

This is a reason to think larva should have more food available when both parents are present than when only one is present. This makes the discrepancy harder to explain.
