Eggs are metallic bronze.
This species may be confused with Euchistus species which are common plant feeding stink bugs. The spined soldier bug has more acute spines on the edge of the pronotum. Eggs are laid in small clusters of 20-30 on leaves of plants. Immatures may be found clustered around the eggs shortly after they hatch. Young nymphs may feed on plant juices but later stages are predaceous.
