I am trying to identify a species of caripillar to explain a phenomenon where 5 of the species were found in a brick corner where no vegetation can be found. I figured if I got some background on their life cycle and diet I could come up with an explanation for this odd behavior.

This looks to be pink-striped oakworm, Anisota virniniensis. Read more about this very common caterpillar https://www.butterfliesandmoths.org/species/Anisota-virginiensis.
I wouldn't spend a whole of of time researching about "the phenomenon". It is highly likely a situation where the caterpillars got caught up in the corner and weren't smart enough to make their way back out.
