Common Teasel
Common Teasel
Dipsacus fullonum
Common teasel, also referred to as Fuller’s teasel, is a biennial or short-lived perennial herbaceous plant that produces a basal rosette of puckering leaves for one or more years, and then sends up a prickly, flowering stem.
Curly-leaf Pondweed
Curly-leaf Pondweed
Potamogeton crispus
Curly-leaf pondweed is a submerged perennial that resembles many native pondweeds. Care must be taken to correctly identify this species. Rigid, reddish-green, oblong leaves have distinct, finely-toothed, wavy edges. The plant's flat, reddish-brown stem grows from 1-16 ft. Most reproduction is from winter buds, called turions.
Dames Rocket

Hesperis matronalis
Dames rocket is a flowering biennial that was introduced in North America in the 1600s. During its first year, it grows as a basal rosette. In its second year, its flowering stem grows up to 4 ft. tall. Dames rocket has alternate, lance-shaped leaves with serrate margins.
Elm Zigzag Sawfly
Elm Zigzag Sawfly
Aproceros leucopoda
The elm zigzag sawfly is still in the early detection phase in North America. Please report all sightings of elm zigzag sawfly through iMapInvasives, to help determine the distribution of this species, ahead of any management efforts. Since most elm trees can recover from elm zigzag sawfly defoliation events, control may not be necessary, and research into management options is ongoing.
Emerald Ash Borer
Emerald Ash Borer
Agrilus planipennis
Emerald ash borer has a golden-green body with dark, metallic green wings and a purplish-red abdomen. Adult beetles average 3/8" to 3/4" long and 1/6" wide. EAB emerges in late spring, flying throughout June to August.

Eurasian Boar
Eurasian Boar
Sus scrofa

European Cherry Fruit Fly
European Cherry Fruit Fly
Rhagoletis cerasi
The European Cherry Fruit Fly has been found on sweet cherry trees along the Niagara River. This was the first U.S. detection of this species and has resulted in a quarantine of parts of Niagara County.
European Crane Fly
European Crane Fly
Tipula paludosa
Commodity:
Hayfields, pastures, turf grass, vegetable and small fruit crops
First sighting:
Erie and Niagara (2004)
Impacts:
Larvae (leatherjackets) feed on roots of hay, pastures, turf grass, sugar beets, turnips, and carrots, damaging growth of the plants.
Larvae also emerge to feed on stems and grass blades on damp, warm nights. Damage can also occur on golf greens from birds pecking out the larvae during the spring.
