Species: Hemphillia glandulosa

<i>Hemphillia glandulosa </i>is hermaphroditic and lays eggs. On Vancouver Island<br>copulating pairs have been observed in the autumn. Eggs are relatively large and<br>deposited in small clusters over several months. The slugs mature within their first year<br>and probably seldom live >1 year. Movements and home ranges are undocumented (COSEWIC, 2003). In captivity, the slugs deposited small clusters deposited by six individuals was 1137 (KO, unpublished data). The eggs were tearshaped, transparent, and about 3 mm long and 2 mm wide. Hatching at ambient temperatures of 915°C took about 3 months and was staggered over a period of several days. This strategy (deposition of many small clutches over an extended period) may be an adaptation to ensure that at least some eggs survive to hatching under unpredictable conditions. Alternatively, it may reflect constraints associated with a small body size. Under natural conditions, eggs may be deposited in the autumn and hatch the following spring. Suitable oviposition sites probably include leaf litter, decaying logs and other woody debris. These slugs are likely short-lived, and perhaps only a few individuals survive to their second year.<br><br>
