This will key
to Tabanus lineola but I am quite certain that it is Tabanus similis, female, which is unusually abundant here in new Brunswick this year. Still a rare fly here but much more abundant than 'normal'.

Tabanus similis
Hi. Thanks for the ID! What do you mean "This will key to T. lineola"?

To correctly
identify most insects one has to consult scientific publicatios for the region where the insect was photohgraphed ( or collected). For your area the publication "The Horse Flies and Deer Flies of New York (Diptera, Tabanidae) by L.L. Pechuman" is possibly the most useful. In this publication there is a method to ID Tabanus species entitled "Key to the species of New York Tabanus I. Females". Such keys are not perfect and one needs quite a bit of experience to be able to interpret them correctly. Using this key for your specimen will lead one to Tabanus lineloa.
