Horse-flies (genus Tabanus) are larger, up to 25 mm (1 in) in length and are mostly dark brown or black, with dark eyes, often with a metallic sheen. Yellow flies (genus Diachlorus) are similar in shape to deer flies, but have yellowish bodies and the eyes are purplish-black with a green sheen. [12]
Diachlorus ferrugatus, commonly known as the yellow fly in the United States or doctor fly in Belize, is a species of highly aggressive biting horse-fly of the family Tabanidae native to North and Central America to Costa Rica.
Many species are brightly colored, with spots, stripes, and bands of yellow or brown covering their bodies. [11] Due to this coloration, they are often mistaken both by insect-eating birds and by humans for wasps or bees; they exhibit Batesian mimicry. Despite this, hoverflies are harmless to humans. [6]
The fly's abdomen and thorax are completely covered in bright yellow and black striped fur, imitative of a sand wasp, and females are thought to not require blood meals to reproduce, unlike most tabanids. Little is known so far about its ecology and habitat, but it likely has a wider range in the Amazon Basin. [2]
The body is black, the hairy abdomen is yellow with black stripes and the wings are brownish but transparent. The compound eyes are well developed in both sexes. They have bright blue-green eyes, with transversal red bands. Adult horse flies can be found in July and August. Males of this species feed on plant juices, while female are bloodsuckers.

Palpi are blackish with black hairs. The compound eyes are well-developed in both sexes. They have an iridescent light green pigmentation, with three blue-reddish transversal bands. [7] [8] The Hybomitra aterrima var. auripila (Meigen) has the abdominal tergites more or less distinctly golden-yellow pubescent on posterior margins. [8] Close-up ...
The adult fly is black to metallic green, and has three yellow bands on its abdomen. Its face is a light yellow with large black compound eyes on either side, and its wings are clear; it is 9–12 mm in body length. [1] The larvae are mature at around 11 mm, and they are yellow-white to salmon brown, with markings of black and white or yellow ...
