|Improving Pest Management with Farmscaping||
Farmscaping is a holistic ecologically-based approach to pest management that emphasizes the arrangement or configuration of plants that promote biological pest management by attracting and sustaining beneficial organisms. Ideal farmscape plantings provide habitat for beneficial insects, suppress weeds, and grow in close proximity to the cash crop without competing for light, water and nutrients. Research has shown that maintaining high levels of species diversity is a key characteristic of a proper functioning agroecosystem. Unfortunately, intensive farming operations including growing large monocultures, regular cultivation, and excessive use of insecticides often leads to a dramatic reduction in arthropod diversity, especially natural enemies that often keep many pest insects below damaging levels. Farmscaping is a technique designed to add diversity back to the system and minimize disturbance leading to increases in natural enemy populations by providing insectary plants as food and shelter resources.

|Leatherwing (Soldier) Beetles||
Beetles in the family Cantharidae are referred to as soldier beetles or leatherwings. The name soldier beetle originates from the elytra (front wings) of one of the earliest described species being reminiscent of early uniforms of British soldiers. The latter name was coined for the soft nature of the elytra. Two species in the genus Chauliognathus are commonly found in Virginia. Chauliognathus pennsylvanicus (Fig 1) is often referred to as the Pennsylvania leatherwing, or the goldenrod soldier beetle referring to its favorite flowering plant in the fall. A similar species Chauliognathus marginatus, the margined leatherwing, is found in the spring on various flowers.
