THE PUPAL CASE OF MALLOPHORA ATRA MACQUART (DIPTERA: ASILIDAE) FROM SOUTH AMERICA

Abstract The pupal case of Mallophora atra Macquart from South America is described, illustrated, and compared with the South American species M. media Clements and Bennett, M. ruficauda (Wiedemann), and M. sylveirii Macquart, and the North American species M. bomboides (Wiedemann), M. fautrix Osten Sacken, M. leschenaulti Macquart, and M. orcina (Wiedemann).

The Pupal Case of a Palearctic Robber Fly, Andrenosoma atrum (Linnaeus) (Diptera: Asilidae)

Abstract. The pupal case of the Palearctic robber fly Andrenosoma atrum (Linnaeus) is described, illustrated, and compared with those of Andrenosoma albopilosum Villeneuve and Andrenosoma bayardi Séguy. A key to the pupal cases of these three species is provided.

Review and analysis of information on the biology and morphology of immature stages of robber flies (Diptera: Asilidae).

Recent publications on the immature stages of robber flies (Asilidae) are reviewed and listed for the 14 currently recognized subfamilies (Asilinae, Bathypogoninae, Brachyrhopalinae, Dasypogoninae, Dioctriinae, Laphriinae, Leptogastrinae, Ommatiinae, Phellinae, Stenopogoninae, Stichopogoninae, Tillobromatinae, Trigonomiminae, and Willistonininae). For the Phellinae there are only limited data on the pupal cases, and for the Tillobromatinae there are only limited data on the eggs (potential oviposition site in soil) and pupal cases. The recent literature is compared with pertinent pre-1972 publications.

A checklist of the Robber Flies (Insecta: Diptera: Asilidae) of Wyoming, USA

A checklist of 158 species of Wyoming robber flies (Insecta: Diptera: Asilidae) is presented for the first time based on personal collecting, literature review, museum specimens, and online databases. In Wyoming, asilid habitats range from arid desert environments to mountainous pine-douglas fir forests. According to the latest classification system of Dikow (2009), these include 54 species of Asilinae, 24 species of Brachyrhopalinae, 10 species of Dasypogoninae, 3 species of Dioctriinae, 23 species of Laphriinae, 8 species of Leptogastrinae, 24 species of Stenopogoninae, 8 species of Stichopogoninae, 1 species of Trigonomiminae, and 3 species of Willistonininae. Thirty-one of these species have not been previously recorded as occurring in Wyoming.

The Pupal Case of a Nearctic Robber Fly, Efferia snowi (Hine, 1919) (Diptera: Asilidae)

Abstract The pupal case of the Nearctic robber fly, Efferia snowi (Hine, 1919), is described, illustrated, and compared with the pupal cases of five other Nearctic species. A key is provided to the known pupal cases of Nearctic Efferia species.

The Pupal Case of a Nearctic Robber Fly, Proctacanthus brevipennis (Wiedemann, 1828) (Diptera: Asilidae)

Abstract. The pupal case of the Nearctic robber fly Proctacanthus brevipennis (Wiedemann, 1828) is described, illustrated, and compared with those of P. hinei Bromley, 1928; P. micans Schiner, 1867; P. milbertii Macquart, 1838; P. philadelphicus Macquart, 1838; and P. rufus Williston, 1885. A revised key is provided to the pupal cases of these species. Observations are reported on emerging adults and a newly emerged female P. brevipennis being captured and eaten by a green anole, Anolis carolinensis (Voigt, 1832).

The pupal case of a Nearctic robber fly, Diogmites contortus Bromley 1936 (Diptera: Asilidae)

Abstract The pupal case of the Nearctic robber fly, Diogmites contortus Bromley 1936, is described, illustrated, and compared with the pupal cases of three other Nearctic species, D. discolor Loew 1866, D. misellus (Loew 1866), and D. neoternatus (Bromley 1931). A key is provided to the pupal cases of these species. The main characteristics of the D. contortus pupal case are, (1) abdominal segment 1 with dorsal transverse row of 30 spurs, (2) abdominal segments 5–7 with uninterrupted ventral row of 41–47 bristle-like spines, and (3) abdominal segment 8 with 8 lateral bristle-like spines on each side.
