Discussion
Facts
- Asexual reproduction by 3 types of buds: 1 thoracic bud, 1 abdominal bud and 5 to 8 postabdominal ones (Ref: Sato1994)
- Larval stage does not feed, lasts minutes to hours at 20 C. (Ref: Sato1994)
- Hermaphroditic; external fertilisation (Ref: Sato1994)
- Length larval trunc is 0.5 mm, width 0.25 mm, so volume is pi/6*0.5*0.25^2 = 1.6e-2 mm^3 (Ref: Mill1970, Carl1952)
