• Question #5998


    What are these bugs on my maple tree? Are they harmful to the tree? Do they bite? Thank you.

    What I would do without BugGuide.net!!?   I couldn’t really see the insects in the picture very well, so in BugGuide’s search box, I typed, “bugs on maple tree trunk.”  And what popped up???– a picture of insects that looked exactly like yours.  They are bark lice.  They do not bite nor do they harm the tree.  Here is the BugGuide link with more information: https://bugguide.net/node/view/83280

    Thanks so much for sending a picture.  I learned something too, this time!
