What Bug is This?

This time of year and into the Spring, these little Largus bugs show up all over the landscape. I usually find them when I'm digging in the ground, getting my garden ready for some new plants. Some people find them clustered on the side of their house, others on plants, and some in the house.

Largus bugs are fairly common bugs, closely related to boxelder bugs and (not as closely) related to stink bugs. Largus bugs are about 1/2 inch long, oval shaped, and greyish black in color, with a red outline around the abdomen as adults. As immatures, they have much more red to their bodies, and black legs.

Largus bugs have piercing and sucking mouthparts, but are generalist feeders. They can be found on oak, wax myrtle, weeds and other woodland foliage. So, very common in our landscapes in South Texas. They rarely cause any damage, so I don't recommend treating for them. If they make their way indoors, just scoot them out - they aren't infesting your home.
If you find them on a sunny day clustered on your house outside, this is pretty common. They are sunning themselves and/or emitting a feel good type pheromone (chemical), that encourages them to cluster or aggregate.
