[ 2 ] Pupation usually occurs in spring at the end of the larval tunnel in the sapwood , eclosion occurs 12–50 days later, and adults will chew out of the tree approximately one week after eclosion.

Spider water beetles can be divided into two species groups, based on morphological and ecological adaptation patterns. [ 8 ] The Ancyronyx variegatus species group are larger in size (usually larger than 1.4 mm (0.055 in)), with very long legs, stout coxites on the ovipositor , and a transverse prosternal process.
