Although pinned voucher specimens are the “gold standard” for identifying insects in surveys, in some circumstances it may be undesirable to kill the study subjects. If insects can be caught be net and then released, digital photographs can record details that improve the accuracy of identifications. We describe a simple piston-and-cylinder holding chamber that quickly, temporarily, and harmlessly restrains bees or similar insects for portraiture in the field. Tested in large surveys of bumble bees in Colorado USA, this device was able to prevent a substantial number of misidentifications.
