> > Now Open for Buggy rentals=2C picnics=2 Angus, Re your access problem, I haven't used the tabanid site for some time, quoted the Deer Fly thing from memory and had forgotten that there was a second key site for bigger Tabanidae like Hybomitra. Just checked both sites from here, got into both readily and could access all sets of images and the starts of the keys, so it seems to work for me as far as I checked: http://cjai.biologicalsurvey.ca/tm_08_08.html [1, deerflies etc] http://cjai.biologicalsurvey.ca/tm_13/t_13.html [2, Hybomitra etc] This was done directly on-line through an Eastlink connection via a Google search, but not using Acrobat -- didn't try to get a PDF file out of it, so maybe that's the problem? Did this at home from my older Mac G5 computer using a now-unsupported Firefox browser that I can't upgrade -- thought that would be worst-case. I haven't tried same from a much newer laptop with a recent up to date Firefox.

At first the Server does not have "adequate bandwidth" & now Adobe Acrobat cannot read it (no dict object?). Has anyone have better luck?

Insect taxonomists, a rare and non-expanding breed, will always want to see the original pinned (dead) specimens to view them from different angles, in order to put their names and valued reputations behind an identification. But it is not part of busy taxonomists' job to do this, so they may do it as an occasional favour to colleagues with plausible professional needs, but good luck and likely no chance if you aren't in this category, unless it's a very unusual specimen or location. On the other hand, some specialists do trawl the submissions to BugGuide and will give non-binding but valuable opinions on the identity of images, without compromising themselves, and BugGuide itself has accumulated consultant 'amateurs' with outside jobs who are just as well informed. > > So someone trying to popularize an insect, the original context here, needs to get the bug identified at least to genus and hopefully to species level in order to start talking at all, and imho there is almost no chance to get this done by professionals: so original specimens are not practically useful for this but good colour digital images are, if submitted to BugGuide.net, Diptera.info (flies) and so on. As you say, color in some cases fades in pinned specimens unless it's an interference colour, so good colour is an added bonus in images of live insects. This is a lesser problem for butterflies where identification mostly depends on wing pattern and colour, and an excellent local resource for this now exists on-line for NS. I think a good field guide for Maine Odonata exists, applicable for NS too. But these are relatively small, easy-ID groups compared to flies, hymenoptera and beetles. Randy will know that an excellent guide for the 25 or so Deer Fly species east of the rockies is available on-line, and there's also a good one for hoverflies, but for most fly families there's nothing. I don't know, for hymenoptera and beetles. > > The gizmo for temporarily holding pinned specimens to rotate them for inspection is a 2-dimensional goniometer, allowing rotation and viewing from almost any angle, adjustable about two axes held at right angles. I once bought one from BioQuip in California. Google to BioQuip's on-line catalogue to see images (under Microscopy) -- they stock two goniometers which they call Microscope Stages, #6188 at US$32.95 (mine) and #6186, $34.95. Both these would be used mainly under a dissecting microscope or with a hand magnifying lens. They are not fancy high-tech and yes you could make the 6188 one -- I once did so on a much smaller scale for use under compound microscopes which mostly have very small working distances, for inspecting insect eye optics from different angles at high power. The Bioquip versions are much too tall to allow this. > Steve (Hfx) > ________________________________________ > From: naturens-owner@chebucto.ns.ca [naturens-owner@chebucto.ns.ca] on behalf of David & Alison Webster [dwebster@glinx.com] > Sent: Monday, July 6, 2015 7:57 PM > To: naturens@chebucto.ns.ca > Subject: See a lot by looking: Re: [NatureNS] Queen Bee > > Hi Steve & All, July 6, 2015 > I didn't intend to limit the concept of suitable magnification, so > something can be seen clearly, to images.
