Habits and Life History:

  • Bee assassin bugs are usually found in meadows, gardens, field crops, mountains, deserts, and coastal regions.
  • Females use plant resins to coat their legs and search for prey. When they capture the prey, it gets stuck within the resin. These resins are also used by female bee assassin bugs in maternal care.
  • Like other members of Hemiptera, Bee assassin bugs also undergo a simple life cycle: Eggs, Nymph and Adult.
  • Female lays eggs in warm season on the surface of leave or stem that are stuck to them.
  • Nymphs come out after hatching and undergo molting 4 times. Some species are reported to molt up to 7 times also. Nymphs are also voracious predators like their adults.
  • The last instar matures into a winged adult.
  • Bee assassin bees have 1 generation per year.
