I get what you mean, we know some insects life cycles and culture etc, so from Aliens it can be too familar to some that recognize that cycle but there is still plenty of alien-ness as well. The intelligence to cut the power, sabotgage a dropship and sneak on board etc. that is a sign of great inteliigence beyond an insect. They would need to know what the power and dropship meant to sabotage it.
Consider though, mystery aside. What did the alien from the first film display that the aliens from the second film didn't? maybe more caution but only because it didn't have numbers.
Remember, different situatuion
