spot the spot

Last week, Jonathan Shields, Agriculture Inspection Manager with the Ohio Department of Agriculture's (ODA) Division of Plant Health reported seeing hatch of the spotted lanternfly (SLF) in Cincinnati, Ohio on Tuesday, April 22, 2025.

As temperatures warm, Spotted Lanternfly (Lycorma delicatula) (SLF) eggs laid last fall will begin to hatch later this spring. The National Phenology Network is forecasting SLF egg hatch in North America based on growing degree day (GDD), base 50F. The map below was captured on Wednesday, April 2, 2025. You can continue to monitor the USA NPN website for SLF egg hatch at: https://usanpn.org/data/maps/forecasts/spotted_lanternfly

This afternoon's BYGL Alert on the Spotted Lanternfly (SLF) is a media release that was distributed by the Ohio Department of Agriculture on Friday, August 4 and is the source the information below.

On Thursday, May 4, 2023, Jonathon Shields, Agriculture Inspection Manager with the Ohio Department of Agriculture (ODA), confirmed hatch of spotted lanternfly (SLF) within the Cincinnati infestation. ODA captured 8 SLF nymphs on Thursday afternoon in the known infested area.

Spring brings much anticipation. Warmer temperatures bring a show of spring wildflowers, blooms of spring flowering trees and shrubs, and insects activity- including the hatch of spotted lanternfly (SLF) nymphs where overwintering egg masses where present.

You have heard about the spotted lanternfly (Lycorma delicatula), and maybe even attended a presentation about this invasive insect pest. But have you experienced it? Have you seen the insect in the field?

Penn State University Extension will be offering a free webinar on November 16, 2022 at 10:00 am titled Spotted Lanternfly and the Potential Impacts on the Maple Syrup Industry.

While there is something to see year round in the world of Spotted Lanternfly or SLF, last week, a group of Extension professionals - Jim Jasinski with our IPM Program, Thomas deHaas in Erie County, Ann Chanon in Lorian County and Amy Stone in Lucas County spent sometime in the field together gathering footage and photographers for some educational resources that are seasonal specific. Once developed, these tools will help Ohioans, help us, look for SLF in the Buckeye State.

On Thursday, October 28, 2021, the Ohio Department of Agriculture (ODA) announced a quarantine to combat the spread of the Spotted Lanternfly (SLF). This BYGL Alert includes information from their release about the new quarantine.
