From: Convergent evolution of saccate body shapes in nematodes through distinct developmental mechanisms
Different developmental stages of Heterodera glycines and size measurements. H. glycines hatches as second-stage vermiform juveniles (J2 s), infects the host root and initiates feeding. Following infection, their body diameter increases resulting in development from a vermiform J2 into a saccate-shaped adult female. Width measurements were made at the maximum diameter.
