Neochlamisus platani is a species in the leaf beetle genus Neochlamisus. This beetle feeds, mates, and oviposits on their host plant American sycamore (Platanus occidentalis), where it prefers young trees.{{cite web|url=https://wiki.bugwood.org/Archive:Sycamore/Neochlamisus_platani|title=Sycamore/Neochlamisus platani - Bugwoodwiki|website=wiki.bugwood.org|access-date=2 June 2019}} Its common name is the sycamore leaf beetle for this reason.

The adult beetle is bronze to brown in color and about 3.5 to 4 millimeters in length. Its exoskeleton is rough and bumpy, helping it to camouflage as a piece of bark or droppings. Both adults and larvae feed upon the foliage of the sycamore. Heavy infestations can begin to reduce the foliage mass of a tree, damaging its aesthetic value as an ornamental.
