Describe the varying parental skills in the arthropod phylum

The arthropod phylum is the largest phylum of the animal kingdom, including among others all the species of lobsters, insects, crabs, spiders and centipedes. Contrary to popular belief, animals belonging to this phylum exhibit a wide range of behaviours. Parental skills or care is a term related to the behaviours involving the protection of eggs and young.
Several species of insects, look after their eggs over the winter and when the eggs hatch, the young stay with their mother, for feeding and protection.
Some species of spiders and scorpions, hold their eggs in a web formation and once they hatch, they hold them on their back until they are able to survive by themselves.

The answer is society was a caste like system with poor whites at the bottom of the white social ladder.
