A botanical garden is a man-made environment with a microclimate in each hall. Despite human efforts to control the environment, insects have invaded the botanical garden and are eating the plants. The gardeners have released cryptobugs – ladybugs trained to prey on the invaders. But since the ladybugs alone can’t control the pests, the gardeners attempt disinfestation. Fumigation kills everything but the resistant bugs. The more they try to rid the garden of the bugs, the worse the invasion becomes.
