Eastern Boxelder Bug

Dear Don,
This is an Eastern Boxelder Bug, a species that often aggregates in large numbers.  Houses with light colored, south facing walls that are in the sun are favorite locations for aggregating.  Eastern Boxelder Bugs are also known to enter homes to hibernate once weather begins to cool.  The aggregations have led to common names like Populist Bug and Democrat Bug.

Eastern Boxelder Bug

Dear Aaa,
This is an Eastern Boxelder Bug, sometimes called a Populist Bug or Democrat Bug because of the large number of individuals that aggregate together, often in the autumn on light colored walls with sunny exposures.  Eastern Boxelder Bugs are also known to enter homes to hibernate when the weather begins to cool.  Interestingly, the Western Boxelder Bug is our current Bug of the Month.

This bug has been found in my bedroom.  I have an air conditioner in my window so I think it’s getting in through the cracks.
It has a red belly and wings but haven’t seen it fly.

I just cut down 2 large white pine trees a couple months ago. Now I am finding what I swear are 1 million of these bugs on my other trees and in the fallen pine needles.
I dont know if they are harmful to humans, my pets or the other trees, whether they should be left alone, removed somehow.
Any help would be appreciated.
thanks,

Eastern Boxelder Bug Nymphs

Dear Bob,
These are Eastern Boxelder Bug nymphs, and although they are harmless, when they are present in large numbers, they can be quite a nuisance.  They are sometimes called Democrat Bugs.

Eastern Boxelder Bug Nymph

Dear Ann,
This is an immature Eastern Boxelder Bug nymph, and immature individuals are known to aggregate in tremendous numbers with adults, leading to the use of the common name Democrat Bug.  Other similar looking, closely related insects that also form large aggregations include the Western Boxelder Bugs and Red Shouldered Bugs.

Hi. Please identify this bug for me. I think it is an actual bug (Hemiptera). Thanks.

Western Boxelder Bug

Dear Lanny,
This is a Western Boxelder Bug and they are known to form large aggregations when conditions are favorable.

Thanks, Daniel. That was fast! I saw a pic of a boxelder bug on your site and thought it looked similar but we don’t have boxelders growing in this area. Does it feed or host on another Southern California plant?
Lanny Kaufer

Hi Lanny,
According to BugGuide they will feed on many species of maple as well as other trees:  “hosts:
Acer grandifolium (Bigleaf Maple), A. negundo (Boxelder), A. saccharinum (Silver Maple), Koelreuteria paniculata (Goldenrain Tree), and Sapindus saponaria (Western Soapberry)  Flowers and young seeds are preferred, so female trees often support larger populations; may also feed on foliage, on sap seeping from wounds on branches/trunks, and on fallen seeds. They will sometimes feed on trees of the Rose Family (Malus, Pyrus, Prunus, etc.) and cause minor damage to commercial fruit (rarely). They are recorded to feed on plants as diverse as Grass, Alfalfa, and Potatoes. It is even common to see them gathered and sucking fluids from other substances such as discarded human food, smashed insects, etc.”

There are Bigleaf Maples in the creek where this one was seen so that would explain its presence.
Thanks again!
Lanny
