Insect and Arachnid Ecology and Behavior

In 1862 Walsh described an aphis under the name of Brysocrypta vagabunda, which had occurred very abundantly on various forest trees in September. Walsh gave this aphid the name vagabunda, meaning vagabond or wanderer because he knew nothing of its life habits having taken only the winged form and this on various hosts. Two years later or in 1864, Walsh associated the aphid causing a large irregular gall on the cotton wood with the aphid he had described as Brysocrypta vagabunda. Aphidologists since that time have generally followed Walsh in believeing that the form which he collected and described was the same as that causing the gall and the name vagabundus has therefore come to be associated with the gall form.
