Abstract:

Some of the horseflies keying to the greenhead horsefly (Tabanus nigrovitattus) in Tidwell's Key to Louisiana Tabanidae may be cryptic species. In order to separate congenerics a dataset was created to explore variation in Tabanid length across salinity zones at different times of the year.

Varying lengths of horseflies in the family Tabanidae which key to the greenhead horsefly (Tabanus nigrovittatus) collected across multiple salinity zones within Louisiana's Coastal Marshes from 2019-05-16 to 2019-09-11.

Purpose:

To explore variation in Tabanid length across salinity zones at different times of the year.

Data Parameters and Units:

Date (mm/dd/yyy), Bay (Barataria/Caillou), Salinity Zone (Low/Mid/High), Latitude (decimal degrees), Longitude (decimal degrees), Length of Specimen Keying to Tabanus nigrovittatus (millimeters)

Methods:

Individuals keying to the greenhead horsefly (Tabanus nigrovittatus) were collected from low, mid, and high salinity zones using canopy traps baited with dry ice from 2019-05-16 to 2019-09-11. Insects were then pinned and measured using digital calipers.
