Imagine a species of insectoids where the females strongly resemble human women and seek out human males, but only after they've mated with their own males (who are more obviously insects), for the ultimate goal of implanting their eggs inside a human host. I call them insectoids because, due to their size, their anatomy will be different from true insects (lungs instead of spiracles to allow them to breathe, etc.). They are social creatures, living in hives or colonies and emerging in late summer/early fall to lay their eggs, and their behavior indicates they have some understanding of human social rules, and they tend to prefer males that are intoxicated or otherwise impaired, but otherwise their mindset is completely insectile.

The idea is interesting and I am not sure if insects mimicking humans for reproduction has been done but insects using humans for egg laying has. I see the potential for some body horror since where would the eggs be planted in the victim? How? Is the human alive for it all? Does the females reproduce exactly like human females and somehow lay their eggs in their victim? Do they have similar sex organs of a human female? Also, is it like any known insect?

The victim would be paralyzed or rendered unconscious just after the act of coitus, and the eggs implanted in the victim's abdominal cavity via a retractable ovipositor, likely through the abdominal wall, possibly using the navel to camouflage the entry point. The human must remain alive for the eggs to develop properly, and when they hatch the larvae begin eating the victim from the inside out. The females are harmless to humans until after they have mated with their own males, which are about the size of a medium-sized dog and are far more insectoid in appearance and anatomy. The females possess a genital orifice between their rearmost pair of legs, used both for mating with their own males and for coupling with human hosts. This orifice, also possesses small mandible-like structures used to hold onto the host when the female injects her eggs.

The species possesses many features in common with several families of parasitoid wasps, particularly Dryinidae [Which will mean they are solitary, not social like the original post says].

Based on what I'm learning about wasps, the social structure of these creature would probably not be a true hive (that is, a queen with several drones and a number of non-mating females) so much as several individuals living together in a colony for mutual defense and care of offspring. The males would primarily serve to defend the colony from attackers, and the females would forage for food and bring back meat (living or otherwise) for the community.

They did learn human behavior by observing humans, though the details of that still need ironing out. Any hosts for the eggs would most likely be brought back to the colony structure and either kept paralyzed or sealed in.
