FURTHER NOTES ON TABANIDAE IN THE FLORIDA 

 EVERGLADES (DIPT.) 



BY C. A. MOSIER, 

 Warden, Royal Palm State Park, Dade County, Florida, 



and T. E. SNYDER, 

 Bureau of Entomology. 



In previous articles 1 on gadflies in the Everglades the writers 

 have recorded the habit, developed by species of Tabanus, of 

 congregating on the bloom and feeding on the nectar of the saw 

 palmetto (Seronao serrulata), especially where this bloom is 

 shaded by the large fan leaves. After the early morning swarm 

 of T. americanus, males are found on palmetto bloom as early as 

 6.45 A.M., which, however, is some time after sunrise. Males of 

 several species of Tabanus feed on the bloom T. americanus, 

 T. trijunctus and T. lineola and may be found there from early 

 morning until nearly dusk. A few females also feed on the bloom. 



In order to capture a large number of the usually rare males, 

 the leaves were cut from about the flowers of saw palmettos at 

 Paradise Key (Royal Palm Hammock) in April. The males of
