Habits and Life History:

  • Soldier beetles interact with flowers very much, therefore, act as beneficial pollinating agents.
  • Soldier beetles spend their winter as larvae and can live up to 1-3 years. They become active during winter and live in plant debris, leaf litter, loose soil, and other areas where high humidity and prey are present.
  • They have a life cycle consisting of 4 stages: egg to larva to pupa to adult.
  • Female lays eggs in leaf litter or on the soil surface, which hatch in almost a week.
  • Larvae are dark brown or dark yellow colored with elongated cylindrical bodies and resemble tiny alligators. They can grow up to 18 mm, after which pupation occurs.
  • Soldier beetles produce 1-2 generations per year.
