Giant water bugs (Belostomatidae), where the male carries the eggs
around on it's back.
Cicada killer wasps are large and charismatic, and I find it interesting
to watch them dig and stock the nest for their young.
There are the weaver ants that use the larvae to knit together their
nests.
(Hmm...lots of interesting Hymenoptera, when I think about it.)
