  1. A = asexual, S = sexual. Reproductive mode was assessed by determining the presence of males directly in field samples only (field), or in combination with laboratory cultures initiated with field samples (culture). N indicates the total number of individuals investigated (in cases where males were counted from field samples only). * = mode of reproduction is uncertain because of the small sample size.
