Life Cycle

The female lays white eggs 1 to 8 deep in the soil in the summer. When the eggs hatch about 18 days later, the larvae feed on the roots of grasses and other plants. In the fall, they crawl deeper into the soil to overwinter. The following spring they crawl up to feed on roots. They emerge as adults in the late spring when the weather turns warm.


Adults are active at night.

It doesn't only fly in May and it isn't actually a bug, but the cockchafer can be seen at the moment and is pretty easy to spot, being the UK's largest chafer beetle.

When seen for the first time, an adult cockchafer can cause a bit of a stir and lots of people find them a little worrying, according to Stuart Hine of the Natural History Museum's Identification and Advisory Service (IAS).

June bug facts you might not know

We have been having an unusually long and active June Bug season this summer and have been getting a lot of questions about them, so here are a few June Bug facts and information you might not know!

June Bug Facts

June Bugs get their name primarily because most often it is when their eggs start to hatch. It most often ranges from end of may to end of June/early July. June Bug’s larva can live from 2-4 years underground before becoming full grown adult beetles.

These bugs are frequently viewed as pests because they do damage both as larva and as adult beetles. There are several species of beetles that are considered “June Bugs” but the most common ones are the Japanese Beetle, Chafer Beetle, Green June Beetle, and Ten Line June beetle.

What June bugs eat

June bug larva tend to do damage to plant roots as well as grass. They like to eat roots in several plants, like trees, grass, and grains. The larva also really likes to eat plants you may have in your gardens like berries and potatoes, tomatoes, etc. You may have a larva problem if you are seeing several brown patches in your yard.

The grass will often peel off very easily without much effort if you have a significant issues with June bug larva. An interesting way to check if you may have an issue is you can flood the affected areas with water and then the larva tends to come up to the surface.

Adult June bugs eat the foliage on different plants and shrubs. They have been known to feed on well over 300 different species of plants. Many of these pests are very active at night and are attracted to lights. If you have yard lights June bugs are often found around them.

Common June Bug treatments

There are a couple options to get rid of June bugs, you can either make pest’s shelter less easy to live in or what they eat less desirable, the later is often the best solution. In other instances strategic pruning of the plant or surrounding plants may produce the desired result. Depending on how far along the season is, you may need to focus on the adult stage vs controlling the larval stage.

At certain times of the year, products that move through tree, shrub, and flower internal systems may be injected into the soil in dosages that will protect the plant from invading and attacking insects without threatening the health of the plant. Other times the treatment is more focused on the larva. We suggest reaching out to a pest control specialist to determine what the best route would be for your pest issues.
