Ouch! :->

There are five species found in Nova Scotia:

Dytiscus verticalis Say
Dytiscus harrisii Kirby
Dytiscus fasciventris Say
Dytiscus alaskanus Balfour-Browne
Dytiscus dauricus Gebler

D. alaskanus is found only in ponds in the central highlands of Cape =20
Breton, but the other four are generally distributed in the province, =20=

particularly D. verticalis and D. fasciventris, which are quite =20
abundant.

They are excellent fliers and can disperse over wide areas, an =20
colonization mechanism, and useful for surviving when small water =20
bodies in which they are found dry over the summer months. They (and =20
other predaceous diving beetles) are often collected in flight =20
intercept traps in forests and other areas that can be quite distant =20
from water bodies. They are also sometimes attracted to lights.

Cheers,

Chris
