Would you report a suspected spotted lanternfly sighting in your Island neighborhood?
The Massachusetts Department of Agricultural Resources and BiodiversityWorks are monitoring Martha's Vineyard for spotted lanternflies, posting notices around the Island and asking residents to report sightings. Only a few sightings have been recorded on the Island so far.
Why it matters
Spotted lanternflies are not dangerous to humans but can harm numerous crops, and early detection gives officials a chance to limit their spread. Massachusetts residents and farmers have a role in reporting the insect before it establishes itself.
Monitoring has recorded only a handful of spotted lanternfly sightings on Martha's Vineyard, and the insect is known to feed on more than 100 types of plants. Officials have not said whether the sightings represent established populations.
The players
Massachusetts Department of Agricultural Resources
The state agency leading the lanternfly monitoring and public outreach effort on Martha's Vineyard, responsible for agricultural and plant health protection across Massachusetts.
BiodiversityWorks
A conservation organization partnering with the Department of Agricultural Resources on the Martha's Vineyard lanternfly monitoring and outreach effort.
The details
The Department of Agricultural Resources, working with BiodiversityWorks, has posted notices at locations around the Island encouraging residents to report lanternfly sightings. The insects drill into plants to reach sap and excrete a sticky honeydew that coats surrounding surfaces.
Timeline
2014: Spotted lanternflies first appear in North America in Pennsylvania.
Late July to August: Nymphs are expected to molt into adults, depending on temperatures.
Late September to early October: Adult lanternflies are expected to begin laying eggs.
First frost of the year: Adult lanternflies die, leaving egg masses behind.
Seasonal Patterns
The spotted lanternfly was first detected in Pennsylvania in 2014 and has since spread as far south as Georgia and as far west as Indiana. The Martha's Vineyard sightings mark a new northeastern extension of that documented range.
Residents who spot a spotted lanternfly on Martha's Vineyard should report the sighting to the Department of Agricultural Resources. Gardeners and grape growers should watch for the insects, which are most attracted to grapevines and Tree-of-Heaven trees.
The takeaway
Early reporting is the most practical tool available, since sightings help officials decide where to focus monitoring before the insect establishes itself. Checking grapevines and Tree-of-Heaven trees is a simple habit for anyone living on the Island.
