You'd get significant sexual dimorphism.

Firstly, there's no reason for the males to be intelligent, there's no apparent advantage to it. It's a lot of energy to burn for such a short lifespan.

Since one sex is intelligent and the other not, you'd need a system by which the females picked partners. Are they strong? They can't risk fighting as males are not disposable. Are they colourful or showy? Devious? A mix of all the above?

Sex balance among the spawn: You'd need significantly more males than females. At least one male for every litter that a female would bear in her lifetime, per female offspring, per litter. They'd have to breed like rodents. You'd probably need to have a flat minimum of one female and four males per litter to increase population at all. This still only allows a maximum of 4 litters per female, which is ridiculously low in the real world.

The males mating to death? Not such a problem. Though in these cases they mate with as many females as they can before they crash and burn, and for some reason nobody has mentioned the elephant in the room that is the praying mantis.
