Brachyopa daeckei (Johnson, 1917), the black-tailed sapeater, is a rare species of syrphid fly that has been observed in northeastern North America.

The lower half of the face is bare laterally, but on each side of the anterior oral margin is a less thickly pollinose area.

The lateral facial stripes are distinct and reaching quite as high as the base of the antennae.

The scutum is grayish pollinose, with five sub-shining lines, the three inner ones slightly diverging, but not reaching the scutellum.

The humeri are ferruginous reddish, The scutellum basal half is diffuse reddish-brown with a conspicuous preapical depression and pale pile.

The pleurae are brownish grayish pollinose, in areas moderately covered with white pollen.

The pile is shining yellowish, obscuring the reddish brown ground color somewhat.

The venter is rather blackish, with thin grayish white pollen and the incisures are reddish.
