There's no question that sustaining native plants is important. But when you connect it to the state of native insects, the presence and health of native plants becomes critical. Many insects have evolved to survive by eating only the plants in their native environments. When the number of native plants is reduced by invasive plants or by introducing non-native species as in gardening, the availability of edible plants for some insects is also reduced. This accounts for the reduction of numbers of diverse species in some areas. Killing off or driving off large numbers of native insects may have dire results for an ecosystem.
