Species: Hemphillia dromedarius

Dromedary Jumping-slug
Species

    External morphology provided in Branson (1972). Anatomy figured in Ovaska et al. (2002). Relatively large slug with visceral puch elevated into a pronounced hump and a part of the internal shell plate visible through a slit in the mantle. Tail laterally compressed, keeled, and tipped with a horn0like protuberance, termed the caudal horn. The predominant color of the mantle and foot is typically gray with cream-colored mottling on the sides; the sole of the foot is pale yellow, orange-yellow, or cream colored (COSEWIC, 2003).

    Food Comments
    The diet of <i>H. dromedarius </i>is unknown. In captivity, the species feeds sparingly on fresh vegetable matter; in contrast <i>H. malonei </i>and <i>H. glandulosa </i>readily consume these foods (KO, pers. obs.). Under natural conditions, the species may be a fungivoredetrivore. The availability of food as a limiting factor is unlikely, unless the species requires specialized food items (such as particular species of fungi or lichens) that are only present in certain forest types or ages (COSEWIC, 2003).<br>
    Reproduction Comments
    <i>Hemphillia </i>dromedarius is a simultaneous hermaphrodite and lays eggs. Branson (1972) reported a clutch size of 5060 eggs for Washington populations. The oval, semi-opaque eggs measured ca. 3.3 mm in length and 2.5 mm in diameter. Oviposition took place in wet or moist decaying wood. Nothing is known of the reproductive biology of the species in British Columbia (COSEWIC, 2003).
