The Hardy-Weinberg equilibrium gives us a tool to observe how populations evolve (or don't). It states that the frequencies of alleles and genotypes will stay the same through the generations as long as there are no evolutionary influences. In other words, our beetles will stay 86% green over time as long as the following requirements are met:
Mating must be random
Population size must be large, so one individual isn't accounting for a significant portion of the gene pool
No migration, meaning individuals can't be entering or leaving the population
No random mutations in the genes being studied
No natural selection on the genes being studied
As long as our beetles follow these tenets, they will be in a Hardy-Weinberg equilibrium. You can imagine that on our unpredictable planet this kind of stability isn't the norm. So what good is this concept? Well, it gives us a sort of baseline. If the population deviates from the equilibrium, we'll know something is up in terms of evolution.
