Lace bugs of summer


There are almost 30 species of lace bugs in North Carolina besides azalea lace bug which

is arguably the most well-known.  Perhaps the next most damaging species is the hawthorn lace bug which attacks common landscape plants such as Hawthorn, cotoneaster, pyracantha.  By this point in the summer many cotoneaster are pretty well bleached out by lace bugs.  This is particularly true of those in sunny locations.  Cotoneaster is also very susceptible to spider mites such as the two spotted spider mite.  Another common lace bug is the sycamore lace bug which attacks (you guessed it!) sycamore trees.  In most cases sycamore trees do not need control measures for this pest although trees in nurseries or that are young or newly planted may need protection.  Lace bugs cause stippling damage to leaves that causes a bleached appearance but also reduces photosynthesis.  This in addition to immediate aesthetic damage lace bugs can reduce growth by reducing photosynthesis.
