Invasive Jumping Worms and Spotted Lanternfly on the Move; September Gypsy Moth and Invasive Plant Webinars

Dear Colleague,

Invasive jumping worms are here in the Adirondacks, and we need your help identifying where they are. Read more below. Spotted lanternfly (SLF) has not been reported in the Adirondacks yet, but you can help be on the lookout for this invasive insect. Find out more information below. If you want to learn more about gypsy moths, check out the September webinars listed at the end of this email. And, on a fun note, maps from each lake surveyed for APIPP by Adirondack Research in 2020 are now posted on our website.

Identify and Report Jumping Worms

Jumping worms are entering their adult stage and can be easily detected. Please report findings in your area to iMapInvasives and help prevent the spread of this invasive species. Jumping worms earn their name from the unique, rapid, side-to-side thrashing motion they make when agitated. Jumping worms are voracious decomposers and devour organic matter and leaf litter very quickly. When done eating dead leaves, they move on to the top few inches of soil and eat roots or rhizomes growing there.

A tell-tale sign of jumping worm infestations is the presence of soil that has a lumpy, coffee-ground-like texture. Where jumping worms are present, homeowners may observe leaf mulch gone missing, garden plants dying quickly, or healthy plants having a hard time surviving due to shifts in soil structure and chemistry. Please read this tip sheet to learn how you can help prevent the spread of jumping worms.

Identify and Report Spotted Lanternfly

Spotted lanternfly (SLF), while a beautiful insect, is harmful to many agricultural plants and to trees such as sugar maple. A dead SLF was recently found in the Adirondacks on a car traveling from out-of-state. This pest is a good hitchhiker! Its egg masses play a critical role in the expansion of its range. SLF can lay its eggs almost anywhere, including cars, boats, campers, bicycles, and snowmobiles. Eggs can also hitchhike on firewood. Please do not move firewood! Great information about SLF can be found on the NYS Department of Agriculture and Markets website.

Lake Maps for North and North-Central Adirondacks Now on APIPP’s Website

APIPP contracts with Adirondack Research each summer to survey approximately 40 Adirondack lakes and ponds for invasive species. Full reports are available on our website. To make it easier for lake associations and interested shoreowners to find details about the lakes they care about, individual lake maps are also available on our website. We have just posted maps for the 41 lakes in the north and north-central Adirondacks that were surveyed in 2020. Check out this link to see if there are maps for your lake. Maps from 2021 surveys will be posted early next year.
