Insect and Arthropod Identification

Insect and Arthropod ID Request

Digital Sample Submission:

  • Complete the Insect/Arthropod ID Request form on-line and send as an attachment to ppdc@osu.edu, including relevant digital images of insects/arthropods, area where sample was seen, and if applicable, plant damage. 
  • When taking photos, include a ruler or coin next to sample to show size comparison.
  • Include as many photos as possible for best identification. 
  • Any images submitted shall become the property of The Ohio State University and may be used for educational or promotional purposes

Physical Sample Submission:

  • Complete Insect/Arthropod ID Request form, print, and include form with physical sample, ensuring form is not damaged.
  • Insect/arthropod identification often requires more than one specimen. Send a handful of specimens to ensure that at least one insect arrives intact and essential parts are not missing.
  • Carefully pack the sealed container of specimens in a crush-proof package, with packing supplies to cushion the inner container.
  • Use an overnight mail service, or mail the package early in the week to avoid weekend at the post office. PPDC doesn't accept weekend deliveries.
