Maybe you could change it so that offspring always spawn facing away from their parent though? As it stands it's just RNG whether or not a bibite survives their bloodthirsty offspring.
Or a different suggestion: if i'm not mistaken, a bibite's attack value doesn't scale with maturity, does it? maybe it should. if an elder bibite 10 times its size could out-heal a baby bibite's damage instead of just getting gibbed instantly it could buy them precious time and even open up a niche for slow-maturing parasitic bibites. The meta right now highly favors quick maturation, as there is no possible benefit to doing so slowly.
