• Polyblastus fulvilinealis

  Polyblastus fulvilinealis is a small ichneumon wasp in the subfamily Tryphoninae. It is a koinobiont ectoparasitoid of sawfly larvae, meaning the host continues development until the wasp larva completes its growth. Females have been observed carrying multiple eggs externally beneath the abdomen, a behavior whose precise function remains unclear. The species occurs in North America and has been documented in Colorado.
