With a little luck you can experience their impressive threat behavior. At rest, however, they are well camouflaged between dry branches and leaves.

Large prey is easily captured. They also like lurking near the ground.

The males are a bit shy and can fall to the ground in case of danger (and pretend to be dead). They then remain motionless for several minutes on their backs.

Females seem to guard their oothecae for several weeks after deposition.

Males and females have lozenge-shaped dorsal shields without particularly large appendages / extensions (in contrast to D. dessicata).
