[7] As in its relatives, A. herberti has an unusual breeding behavior where the female attaches the eggs to the male's back and he takes care of them until they hatch into nymphs.

[8] A. herberti is a sit-and-wait predator that catches small animals, especially invertebrates such as other aquatic insects and snails, but also small vertebrates such as young fish and tadpoles.

[7] Small and medium-sized prey items are caught with their strong front legs and stabbed with the proboscis, which injects a saliva that both incapacitates the prey and dissolves it.

[7] The largest food category (animals 1.2 cm [0.5 in] or more in length) are mostly scavenged.

The only prey they regularly catch alive (not just scavenge) in the largest category is nymphs of their own species.
