Carnivorous predator; feeds on insects such as caterpillars, beetles, aphids, and bees by injecting lethal saliva into its prey.
Behavior Patterns
Diurnal predator known for its characteristic 'cog-wheel' or 'crest' on its thorax. They are slow-moving and generally solitary, using a long proboscis to hunt and feed. They undergo a simple metamorphosis with one generation per year.
