Desert Spider, Stegodyphus lineatus, one of the best-described species that participates in matriphagy Matriphagy is the consumption of the mother by her offspring.

Endosymbiosis with micro-organisms is common in insects, with more than 10% of insect species relying on intracellular bacteria for their development and survival. [73] Aphids harbour a vertically transmitted (from parent to its offspring) obligate symbiosis with Buchnera aphidicola , the primary symbiont, inside specialized cells, the ...
