I do enjoy searching through the database, the journey is half the fun but need to start using keys.

i must admit, i strongly prefer not to use keys, unless i have a good synoptic collection handy [or a resource like BG] to help rule out ID options --otherwise the experience will be most frustrating, i promise.
with the anthribids, as in most cases, keys would only work with specimens under 'scope; the best printed sources for this family are(1)(2) (both listed @ the family page); the key to genera in AmBeetles follows(1)

I have found that the keys I have often fail me because the anatomy they refer to isn't in my photo.

believe it or not, some keys to subfamilies out there would ask you about details of maxillae or even genitalia in the very first couplet --who needs a better example of a non-starter...
on the other hand, rummaging thru BG pages simply to learn what's what is time very well spent; i would even go as far as saying that it's the best way to familiarize with the local fauna --then you start using keys as a means to find out what to look at.
one lesson you'll soon learn is that it can take hours and dozens of steps to figure out a bug that is otherwise immediately recognizable from gestalt; once you have a reasonably rich gestalt library in your mind, you will start keying things out from the right spot in a key, rather than from couplet one.
in short, we don't have to open every cat to make sure the spine is there, once we know it's a bloody vertebrate

of the different groups are becoming a lot more obvious to me. There are just those times when I search for ever and don't find what I'm looking for that I think if only a key could lead me to the family that is eluding me. White's visual key in his Peterson Field Guide sometimes helps, but more often than not it fails. 1st abdominal segment divided by hind coxae? I put the book down...

but not always helpful for images (key characters may not be readily visible). The usefulness of the key can also be on how 'up-to-date' it is.
For my group (Elateridae) most keys in revisionary works are great. Keys in regional treatments (Downie and Arnett 1996) are less helpful.

Have you thought about collecting specimens for BugGuide's Voucher Program. Your images are very nice and to be complemented by a voucher specimen in a reference collection would be great. Personally, I take Elateridae and Throscidae, but others take other groups (Carabidae to Peter Messer, Buprestids to Kyle Schnepp or Josh Basham, etc.)

and I will consider it. I have always kind of thought of them as my little friends. I talk to them and such... :) It would allow me to capture a lot of bugs that I miss because the creature,(and beetle seem to be notorious for this), drops to the ground and disappears as I try to get close enough to focus.
