Giant Water Bug
One of the largest true bugs. Powerful predator that catches fish, frogs, and even small snakes. Males carry eggs on their backs until hatching. Known as "toe-biters."
Did You Know?
Giant water bugs are devoted fathers — males carry up to 100 eggs on their backs for weeks, regularly doing push-ups at the water surface to keep eggs oxygenated.
Japanese Subsocial Shield Bug
A subsocial shield bug where mothers carry drupes of a specific tree to their underground nests to feed their nymphs. This provisioning behavior is exceptionally rare among true bugs.
Did You Know?
Mothers repeatedly leave the burrow to collect and carry fruit back to their young, one of the only true bugs to provision offspring.
