Abstract Seasonal activity and reproductive phenology
of six forest-inhabiting, common New Zealand endemic carabid beetles, Zolus
cf. femoralis Broun, Holcaspis mucronata Broun, Megadromus
capito (White), Megadromus turgidiceps (Broun), Plocamosthetus
planiusculus (White), and Ctenognathus adamsi Broun, were studied
by pitfall trapping, ageing, and dissecting of females. Beetles were collected
from forest fragments in the Manawatu region, North Island, in 1990-92 and
1999-2000. Two distinct activity periods were distinguished, in the (austral)
spring (August-September) and in late summer-autumn (January-April). Five
species collected were reproductively active in both seasons, although no
teneral beetles were found in spring. A sixth species, M. turgidiceps
was active on the soil surface only in autumn. Results from ageing suggested
that the larger species in the tribe Pterostichini lived longer than 1 year
and could reproduce more than once.
