Mating trials
Mating trials demonstrated that each morphotype within the N.
ingens complex could successfully copulate with its own morphotype and
with other morphotypes (Table 3 ). While we observed a reduction
in successful mating in experiments involving N. ingens , this
also occurred when N. ingens males were paired with N.
ingens females, suggesting that it may have been linked to reproductive
status (e.g . reproductive diapause). Successful copulation
occurred across all combinations of morphotypes, although not always for
both male and female directed crosses. We note, however, that sample
sizes are small.
