Arthraxon grass discovered on Long Island (SEPT 2015)

Arthraxon, (Arthaxon hispidus) is an invasive grass that can be found in many of the same places that Japanese Stiltgrass grows; floodplains, shorelines, wet meadows, wet trails and roadsides. It was found in the summer of 2015 for the first time on Long Island near Big Reed Pond in Montauk.  There are only three other localities known from New York but it is a big problem in states south of New York. Keep your eyes open for this invasive grass by looking for the wide clasping leaves that have very long cilia toward the base of them.  You can Google the scientific name for more information.

Kudzu Bug Makes Rapid Progress Toward New York

The exotic kudzu bug, Megacopta cribraria, was first found in Georgia in 2009 and is now found as far north as Maryland and Delaware.  This stink bug eats kudzu but also eats soybean and possibly native legumes like hog peanut.  It also gathers in large numbers on the sides of houses. We will monitor the kudzu infestations we have in New York to see if or when it arrives. We are in the process of surveying and updating all of our kudzu locations in New York this summer.

More information about the bug and a distribution map can be found by CLICKING HERE
