Green Lacewing
So here is a list of “bugs” to find photos of on the internet so you’ll feel more comfortable with
them, possibly appreciate and respect them, and hopefully won’t kill them. Included are some
things they eat that make them helpful to us.
Assassin Bug:eats flies, leafhoppers, Japanese beetles, tomato hornworms
Beneficial Nematodes: eat cutworms, billbugs, and especially Japanese beetle larvae
Braconid Wasps: eat tomato hornworms, armyworms, cabbageworms, codling moths, gypsy
moths
Brown Lacewing: eats aphids, mealybugs, scale insect nymphs
Damsel Bugs: eat aphids, small caterpillars, thrips, leafhoppers
Damselflies: eat many kinds of bugs plus aphids off of plants
Dragonflies: eat mosquitos, flies
Green Lacewing: eat aphids, other soft-bodies insects
Ground Beetles: eat cutworms, slugs, snails, gypsy moth larvae, root maggots
Ladybird Beetles (a.k.a. Ladybugs): eat aphids, scale insects, thrips, mealybugs, mites
Rove Beetles: eat mites, aphids, springtails, nematodes, fly eggs, fly maggots
Tachinid Flies: eat caterpillars, beetles, sawflies, borers, green stinkbugs
Tiger Beetles: eat ants, flies, aphids, grasshoppers
Whitefly Predators: eat whiteflies

BENEFICIAL
BUGS
This column has put emphasis on using native plants in our gardens. There is, however, a non-native but naturalized plant that can be especially beneficial in our lawns. It’s White Clover. To
understand the benefit of White Clover, one needs to look at the process called “nitrogen fixing” in the soil. Although there is a lot of nitrogen gas in the air, (about 80% of our air), it is not usable by most organisms.
Legumes, such as peas, beans, and clover, form a symbiotic
relationship with nitrogen-fixing bacteria in their roots, called Rhizobium, which live in structures called root nodules. In this relationship, the bacteria convert nitrogen gas from the air
into ammonia, which the plant can use, and the plant provides carbohydrates to the bacteria.
These are called nitrogen-fixing bacteria. The process is more complicated than that, but the part described here is the aspect of the nitrogen cycle that makes nitrogen available to plants. The nitrogen gets into herbivores and humans when they eat plants. When carnivores eat the herbivores they, too, acquire nitrogen.
So that demands the question: Why would so-called landscapers kill the White Clover, which is providing a free service, and charge us to have nitrogen put into our lawns?
The answer is obvious.
