The Spotted Lanternfly (SLF) has been a newly highlighted pest in the region for the past five years, since it’s introduction to Pennsylvania in 2014. Until late in 2018, SLF had not been observed in Maryland. Now it has been confirmed in Cecil County, MD and continues to be found in 13 counties of Pennsylvania, Delaware, Virginia and New Jersey.
The full impact of the feeding habits of SLF have yet to be identified. However, the broad range of fruit hosts that this pest frequents make it a concern for orchards and vineyards. Eggs will be hatching from late April into early May from grey waxy egg masses that are discretely laid on basically any vertical surface ranging from vehicles to tree trunks. The first signs of nymphs will be a black-bodied form with tiny white spots which will develop into a secondary nymphal form that is distinctly red and black with white spots. Adults will appear mid-July and can be spotted as large (one inch long) insects with grey-spotted front wings and bright red hind wings.
Visit the Carroll County Extension office for a free ID card to use when scouting for these invaders.
