The IDL can provide an insect ID for $25
Do you have an insect problem – or an insect you’re interested in – and want to know what it is, or more about it?
For directions on how to send us samples or email photos (or both) for identification at the IDL, click on this link:
At Cornell’s Department of Entomology the Insect Diagnostic Lab can help identify insects and related arthropods, and provide management suggestions if needed. There is a $25 fee, for samples or photos submitted to the lab for an ID; these funds allow the Lab to remain open.
Do you already know what you have, or want more information? We have a number of factsheets available. For descriptions of a variety of insects and related organisms, and (if an indoor or outdoor pest) control recommendations, click on this link below:
In the Northeast, several kinds of outdoor insects are attracted to houses and building walls in autumn, searching for sheltered places to overwinter. Any that find gaps or openings can end up inside. During winter and spring on warm days you may see them indoors. Click on the LIST OF FACTSHEETS for information on any of these – as well as many other indoor pests, and outdoor species found on garden plants and trees.
Spotted Lanternfly –
A new invasive pest of orchards, vineyards, and tree-of-heaven (Ailanthus), the Spotted Lanternfly (“SLF”) has been found in southeastern Pennsylvania and Virginia, and is continuing to show up in new locations in 2018, including 2 sites in New York State. For a recent news article see: https://www.bloomberg.com/news/features/2018-10-02/america-isn-t-ready-for-the-lanternfly-invasion?utm_campaign=news&utm_medium=bd&utm_source=applenews
For updates on Spotted Lanternfly infestations and other information, see: https://www.aphis.usda.gov/aphis/resources/pests-diseases/hungry-pests/the-threat/spotted-lanternfly/spotted-lanternfly
In New York State, anyone that suspects they have found SLF is encouraged to send a photo to firstname.lastname@example.org. (Note the location where the insect was found, egg masses, and/or infestation signs)
Anyone that visits the Pennsylvania or New Jersey Quarantine Areas should thoroughly inspect their vehicle, luggage and gear for SLF and egg masses before leaving and scrape off all egg masses.

Spotted Wing Drosophila – an invasive fly species has been causing fruit damage in the Northeast. Raspberries, blackberries, late-maturing blueberries, day-neutral strawberries, elderberries, cherries, and peaches are among the vulnerable crops. For details see: http://www.fruit.cornell.edu/spottedwing/pdfs/SWDgarden.pdf Because this species resembles other fruit flies, we recommend that you make sure the ID is verified before doing any major control measures.

Common IDs each year – Are you curious about what kinds of things are sent in for identification? This file (click here) lists the most frequently-submitted IDs for indoor samples, 2008 to 2018. The second page lists examples of garden, yard, and house plants people have sent samples from. In 2018 the most common indoor categories were No biting pest (Miscellaneous debris), and Carpet beetles.
