Specimen Intake: Dead insects or pictures only please

Please do not bring live bugs in to the Extension office.  Soft-bodied insects such as aphids, caterpillars, and other worms should be placed in alcohol. Hard-bodied insects should be placed in a zip-lock bag and frozen.  It is important that insects are not crushed and have all their parts intact for correct identification. Pictures of the insects can also be e-mailed to the agriculture agent or brought into the office for identification.
