Thanks, Chris. I knew &quot;Beetle 2&quot; was a Diving Beetle but could
not find a match in books or on the Net. I once had a Diving Beetle land
on my bare chest and bite!! In my experience they fly around quite a bit
in the evenings and may land on anything.<br>

This is a distinctly marked beetle but I could not find a match for it
(Unknown Beetle4)..<br><br>

Unknown Beetle 4 is <i>Carabus nemoralis</i> M=FCller, a large introduced
European ground beetle first found in North America in NB in 1870 and in
NS in 1924. A very useful garden species, it preys to an important degree
on slugs and earthworms.<br><br>
The next three URL's (below) all go to this same image, but the next
picture in the sequence, Unknown Beetle 3a is also a ground beetle (in
the Carabidae), quite possibly <i>Poecilus l. lucublandus</i> (Say) (I
can't quite make out enough detail to be sure). It's a common and
widespread native species in Nova Scotia that are predators on a very
wide variety of insects and invertebrates.<br><br>
&nbsp;Unknown Beetle 3 is also of <i>Carabus nemoralis</i>.<br><br>
&nbsp;Unknown Beetle 2 is a female <i>Dytiscus verticalis</i> Say, one of
the large species of predaceous Diving Beetles (Dytiscidae). The females
have prominent grooves on the elytra, the better for the males to get a
grip on them when mating! <br><br>
&nbsp;Unknown Beetle 1 is a tiger beetle (Cicindelinae). It looks to me
like <i>Cicindela l. longilabris</i> Say, but Derek may want to comment
further.<br><br>
Hope this helps.<br><br>
Cheers!<br><br>

This one has somewhat the same markings as the above but the dorsal is an
iridescent green (Unknown Beetle3)<br><br>

Ignore the dust in the striations of the abdomen (Unknown
Beetle2).<br><br>

And this is the underside of the same beetle (Unknown
Beetle2-Underside).<br><br>

Finally this is a pic (not that sharp) of a beetle that flew by me and
landed on the path (Unknown Beetle1).<br><br>
