  • a female phorid fly (Pseudacteon obtusus)  flies above red imported fire ants (solenopsis invicta) searching for an ant to implant with an egg. She uses the stabbing part of her ovipositor to pierce the thorax and implant the egg. After the egg hatches the larvae migrates to the ant's head, and kills the insect. This type of fire ant is an invasive species imported from South America, and the phorid fly is being introduced to parts of Texas to help control the population of introduced fire ants.

  • Cinnabar moth (Tyria jacobaeae) on Tansy ragwort (Senecio jacobaea) at Cascade Head Preserve on the Oregon Coast. The cinnabar moth was first introduced into Oregon in 1960 to contraol non-native, invasive, tansy ragwort.  Subsequent research has shown that the cinnabar moth can reduce ragwort populations by 50-75% on sites favorable for their survivorship (Isaacson and Ehrensing 1977).  Adult cinnabar moths begin to emerge in late spring/early summer.  Mating commences quickly, and females lay their eggs on the underside of ragwort leaves.  Larva hatch in about two weeks and begin feeding on ragwort foliage.  By the third instar, larvae have migrated to the top of the plant to feed on the buds and flowers. With a good population of larvae, plants are stripped of flowers, buds and leaves.

  • Medusahead (Taeniatherum caput-medusae) is a winter annual native to the Mediterranean region of Eurasia. It is one of the primary range weeds in the western United States. It is a serious threat to native grasslands with complex plant communities degraded to a low seral state. Medusahead is an aggressive competitor with other plants including other annuals in native prairies. A low-value forage species for livestock and wildlife, it has been estimated that the carrying capacity of rangeland for livestock and wildlife has been reduced by 75 percent after medusahead invasion.

  • A cinnabar moth (Tyria jacobaeae) in flight at the Cascade Head Preserve on the Oregon Coast. The cinnabar moth was first introduced into Oregon in 1960 to control noxious ragwort weeds.  Subsequent research has shown that the cinnabar moth can reduce ragwort populations by 50 - 75% on sites favorable for their survivorship. Adult cinnabar moths begin to emerge in late spring/early summer.  Mating commences quickly, and females lay their eggs on the underside of ragwort leaves.  Larvae hatch in about two weeks and begin feeding on ragwort foliage.  By the third instar, larvae have migrated to the top of the plant to feed on the buds and flowers. With a good population of larvae, plants are stripped of flowers, buds and leaves.
