 Comment I prefer other images in the gallery. I would use them for identification purposes. For VI nomination of dragonflies two are normally needed for identification - a side view and a dorsal view and this is also the only way to get the whole insect in focus. A three-quarters view is a bit of a compromise. Of course, if this was the only image available it would be VI. Also, the scope should say male (or adult male) as this insect is diamorphic.

  •  Comment We must add a geocoding. --Medium69 You wanted talk to me? 12:13, 26 November 2015 (UTC)[reply]
  •  Comment @Medium69: That raises an interesting question. Is there a recommended best practice for approximating geolocation for those cases when pinpoint accuracy isn't crucial and there are privacy-related reasons for not being too specific? @Charlesjsharp: How interesting. Sorry, this is the first time I've submitted anything. It sounds like you know more about the subject than I do -- do you know that it's a male or is that just an example? Perhaps you could recommend which in the scope/category you would select? In fact I chose this one as what, to me, looks like the best "compromise" :) It looks like there are three main options for dorsal, of which the best would probably be this one if getting the entire body in the frame is important or this one for detail/macro? As for side view, probably this one or one of these. Perhaps you would prefer to nominate one of the others yourself. If not, however, in the highly likely event that the best images are not ones that I uploaded, is there any issue with nominating other people's images? Sorry for my long comment -- trying to learn :) — Rhododendrites talk  22:31, 26 November 2015 (UTC)[reply]
    Geocoding must be as accurate as possible, but if you are not able to find the exact location, you can specify a larger area. We should see the model {{Location}} for wider geolocation. --Medium69 You wanted talk to me? 23:23, 26 November 2015 (UTC)[reply]
    • Hi @Rhododendrites: Typically males are blue and females yellow, but immature males look very similar to females. There are dozens of good dragonfly sites where you can search (mine is really only useful for UK specimens) - look in Google images as a first step. I only have time to nominate my own images (unashamed self-interest!). For your species there are a couple of very good side views in the gallery - you have uploaded the best dorsal view but is too cropped to be VI. Photographers try to get head and the end of the abdomen in focus for side view and also the wings in focus for dorsal view - User:Quartl is one of the best on Wikipedia. You'll see my QI and VI images on my home page and scopes include: male, adult male, female, immature male, mature female, head - for damselflies there are often many female forms and they get their own scope.

      • @Charlesjsharp: This is helpful. Thanks all for the advice. You or anyone else can go ahead and close this one out as not promoted. :) — Rhododendrites talk
