Beneficial Bugs: Lacewing
Besides being an ingredient in polyjuice potion* the lacewing fly is also helpful as a predatory insect. It is actually bred specifically to be released into greenhouses to control pest populations and reduce the amount of pesticides needed! The lacewings are sold and distributed as eggs because when kept in close quarters they’ll turn cannibalistic. The eggs are then distributed through a garden, greenhouse, or field and the eggs hatch and the larvae eat problem insects. One lacewing can eat as many as 150 aphids a week! The list of pest bugs that the lacewing eats is too long to put here, but they are especially keen on mealy bugs and aphids.
