Scentless Plant Bug

Scentless Plant Bug

Hi again Heather,
Bug #2 is a Scentless Plant Bug, Niesthrea louisianica, and it has no common name.  According to BugGuide, it:  “Feeds on flower buds and seeds of plants in the Mallow family (Malvaceae), such as Hibiscus and Rose of Sharon.
”  More importantly, BugGuide also indicates it is:  “Used as a control of the invasive annual weed, Velvetleaf (Abutilon theophrasti). In one 1987 study mentioned here it was found to reduce seed production by 98%.”  The brightly colored immature nymphs in your photo are wingless, but your photo also shows a winged adult, though the individual is not the point of focus in your photograph.

  1. So “Scentless Plant Bug” isn’t the common name?
