Spotted lanternfly (Lycorma delicatula) has spread to the WNY PRISM region. In mid-September, the Department of Agriculture and Markets (AGM) confirmed the presence of spotted lanternfly in Buffalo. Based on a report made to AGM, they conducted surveys in and around the reported sighting and over 100 adults were found.
Spotted lanternfly is an invasive species that feeds on more than 70 plant species, including trees and crops such as grapevine, apple trees, and hops. First found in New York State on Staten Island in August 2020, spotted lanternfly has quickly become a high priority target for the state.
Spotted lanternfly (SLF) adults emerge in July and have eye catching wings with forewings that are grayish with black spots, and hindwings that are red with black spots. Adult SLF begin laying eggs in September and eggs hatch in late April to early May. Surveys for SLF egg masses can be conducted throughout the winter. Nymphs emerge in spring and are black with white spots and turn red with white spots before becoming adults.
If you find SLF in the WNY PRISM region, immediately report the species to AGM. In addition, please follow these simple steps:
WNY PRISM received ten SLF traps for the 2022 field season from AGM and reached out to land managers and community scientists to help place and monitor these traps. The best way to detect this insect is to set up traps on another invasive species, tree of heaven (Ailanthus altissima). This tree is native to the same area in Asia as SLF, and the insect is drawn towards this species for feeding. The traps are simple funnel traps that use metal screen wrapped around the trunk of the tree to guide SLF into a collection bag. Our dedicated volunteers and partners check the traps bi-weekly, and report back to WNY PRISM with their findings.
