Tabano

Tabano is the common name used in Italian and Portuguese for horseflies, a group of large biting flies in the family Tabanidae. The term covers various genera within the group, including those known for their bold eyes and stout bodies. In English, the same insects are generally referred to as horseflies or gadflies, but tabano remains the local name in several Romance-language contexts.

Adult tabanos are robust insects with strong wings and prominent mandibles. Females, which require a blood meal to mature eggs, commonly bite mammals, including humans, delivering a painful sting. Males typically feed on nectar and do not bite. Eye coloration and patterns can be distinctive in different species, sometimes producing iridescent or banded effects.

Life cycle and habitat: tabanos undergo complete metamorphosis, with eggs laid in clusters on vegetation near water. The larvae are aquatic or semi-aquatic, living in mud or moist soil and feeding on invertebrates or organic matter. Pupation occurs in the surrounding substrate, and adults emerge during warm months. They are most common in wetlands, riverbanks, meadows, and forest edges where breeding sites and hosts are available.

Ecology and impact: tabanos can be significant pests to livestock, causing stress and reduced productivity due to repeated biting. They can also act as mechanical vectors for various pathogens, though they are generally not primary disease reservoirs. Control measures typically emphasize protecting livestock and people with protective clothing and screens, as well as habitat management to reduce breeding sites and the use of repellents where appropriate.

Notes: the term tabano is primarily a linguistic designation for these insects rather than a taxonomic group with a single species, reflecting the broad range of horsefly species represented in regions where the word is used.
