They are the medics of the hive, with the ability to heal things that are directly next to them (around 400-600 hp at CL 10.0).
Healing take the place of an attack. (They instead turn and zap their patient.)
They follow an interval when healing (4 attacks and then a heal.)
They won't heal anything if their own health is below 60%.
They won't heal anything if they can't attack you. Basically, they love chasing their target first and foremost.
When they hit a player, they put the "Zapped" debuff on them, significantly lowering their accuracy for a while.
They are the smallest non-Fluff monster.
Beginning at wave 6, the Shockroaches gradually are replaced with lightning bugs at increasing frequencies. After wave 45, all roaches begin to be replaced with Deathroaches
