What Bugs in Oregon Will Be Attracted to My Trees?


Do you like the idea of entertaining bugs in your garden or are you a little averse to it?

You’ll be amazed to know that many insects are beneficial and actually improve soil, pollinate plants, or kill off nasty insects that harm plants. Of course, there are also different kinds of bugs in Oregon that will ruin your plants. These are nothing short of a nuisance.

Many bugs will be attracted to your trees, but don’t worry too much about them ruining your beautiful yard or garden. With proper knowledge about bugs in Oregon, you can take care of your garden and keep your trees healthy.

Let’s look at some insects and bugs that might, or might not, be helpful to your plants and trees.


You’re wrong if you believe that ladybugs are dangerous. Most people enjoy having these bugs in their yards because they add color. Some people also believe they’re a lucky charm if they land on you.

As a matter of fact, ladybugs are actually good for plants and trees. They kill dangerous insects like aphids and mealybugs. So ensure your trees are pruned often to attract ladybugs to your yard.

Green and Brown Lacewings

Green and brown lacewings are commonly found to be useful bugs in Oregon. Like ladybugs, they feed on mealybugs and aphids.

These bugs have long antennas and mouthpieces, both of which help them identify their prey quickly and eliminate them for you. They are either green or brown in color with net-like wings. You’ll find they’re a welcome presence in the garden, keeping infestations of destructive pests at bay.


The Nabidae family includes the “damsel bug,” called this because they hold up their front legs, which seems as though they’re lifting a dress hem while walking or dancing. These forelegs are used to capture their food. Such bugs in Oregon are beneficial for your trees because they prey on dangerous insects like aphids.

In particular, if you have fruit-growing trees in your garden, Nabidae bugs will feed on several plant pest types.

Apart from their long and thin legs, the big, bulbous eyes of Nabidae bugs are what tends to make these bugs pop out on your trees.


Tomato Hornworm

These bugs may look good, making you believe they’re an asset to your garden, but they’re a dangerous bug for your trees.

The larvae are the start of the problem: they feed on your trees. Tomato hornworm larvae are large, green caterpillars. They have horns around their heads and stripes on their bodies. They can easily blend into your trees, which makes them hard to see.

As they evolve out of their larva stage and into the adult stage, they gradually develop a grey color with orange spots on the sides of their abdomens. Tomato hornworms will eat your plants when they’re in both the larva and adult stages.


Aphids are another harmful species of bugs in Oregon that you want to avoid having in your trees. Aphids are sapsuckers that prey on the stems of the leaves, seeds, buds, and bark. They’ll even cause damage to trees’ root tissue.

They’re like chameleons because they change their color depending on the trees they reside on, and due to their small frame, they’re hard to recognize.

The harm generally caused by these bugs tends to be insignificant, but they may have a negative impact if not dealt with. These insects, for example, create honeydew, which can promote the development of black sooty mold, a dark-colored fungus, when it grows on the surrounding plant tissue. If the fungus grows too thick, it can block sunlight from the leaves of your tree, stunting its growth or even causing early leaf drop. The honeydew can also attract additional pests to your trees, such as ants.


Mealybugs are another Oregon bug that isn’t helpful for your trees, but they’re quite common, especially when the weather is a little warmer. They usually prefer to attack the plant’s sap.

They are mostly found on sunflowers, orchids, and ferns, and are usually seen with ants. You can find their whereabouts on your trees by following the ant’s trails, which is an advantage for you. And you’ll know when you find them because these bugs look somewhat like white cotton on trees.

The good news is that mealybugs are eaten by both ladybugs and lacewings, making this a natural and healthy way to get taken care of these bugs.

Azalea Lace Bug

Azalea Lace bugs are not helpful to your trees at all, unlike the green and brown lacewings. They multiply rapidly and can survive several generations a year. They prey on your trees’ sap and spread infection. They’re most prevalent in mid- to late May.

You can regulate these bugs using organic insecticide soap or horticultural oil. In general, however, it’s advisable to not use insecticides because they can destroy the healthy bugs.

These are just a few of the bugs in Oregon that you might find on your trees and in your garden. Some will protect your trees, while others can cause damage.
