Do you have an insect problem — or an insect you’re interested in — and want to know what it is, or more about it?
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.
Click here for directions on how to send in samples or photos for identification.
Do you already know what you have, or want more information? We have a number of factsheets available. Please feel free to take a look for descriptions and control recommendations.

Spotted Wing Drosophila (SWD), a new invasive fly species originally from Asia, has been causing widespread injury to some fruit crops in New York State. Raspberries, blackberries, late-maturing blueberries, day-neutral strawberries, elderberries, cherries, and peaches are among the vulnerable crops. A factsheet on the Spotted Wing Drosophila is available from Cornell Cooperative Extension at: 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. For the latest information from NYS Integrated Pest Management on SWD, go to: http://blogs.cornell.edu/SWD1/
Have you ever wondered how insects are identified, and how it has changed over time? In this 30 minute webinar http://vimeo.com/54970615 our diagnostician Jason Dombroskie discusses Trends in Insect Diagnostics.
Are you curious about what kinds of things are commonly sent in for identification? Follow this link for IDL Top Spp tallies Jan2016 which includes the most frequently-submitted kinds of samples in the past few years from indoors, and also a list of the types of garden, yard, and house plants people have sent samples from, for pest identification. In 2015 the most common indoor categories were No biting pest in sample, Bed bug, and Carpet beetles. However, two-thirds of the samples people were concerned might be bed bugs, turned out to be something else.
