Tiger beetles of the Genus Cicindela (Coleoptera: Cicindelidae) apparently have few natural enemies. About seven per cent of the larvae of Cicindela scutellaris lecontei Hald, are parasitized by larvae of Spongostylum anale Say (Diptera: Bombyliidae) according to Shelford (1909, 1913). Frick (1957) notes egg deposirion by a “small black bombyliid fly” in the larval burrows of Cicindela in Washington State. Wallis (196l) has seen large asilid flies capture tiger beetles on the wing. He believes that the asilids attack only while the Cicindela are in flight and vulnerable areas are exposed; the beak is inserted in the softer parts just behind the scutellum.
