   How to collect a sample

Insect ID Capture insects and immediately kill by freezing. Leave in freezer overnight. Pack gently with tissues or cotton in a stoppered vial. If desired, include sample of damage. Do not place butterflies, moths, or bees in alcohol, as key diagnostic features will be ruined. Do not send live insects, crushed insects or insects caught on tape or on sticky traps. squashbugs

Many problems originate belowground in and around roots‐‐ include roots and soil for more accurate diagnosis! Please do not submit dead, dry, decayed or rotted samples as they provide insufficient material for diagnosis. plant disease

Plant ID Plants are classified on floral morphology and identified using various plant parts including flowers, fruits, leaves, buds, and
stems. Send as much plant tissue as possible to give a good representation of the whole plant.
