Re: Of Armies and Agriculture

Thanks Lou and Hayath, much appreciated. Lou- I use the same technique when photographing raids, sometimes a little vaseline towards the top of the boots will also help discourage the stray entrants. You can't spell beware without aware... One must certainly be very self-aware of one's position, oth...

Re: Of Armies and Agriculture

Thanks everyone, most appreciated. Lou- Army ants I find to be very situationally dependent. When they are raiding they are exceptionally aggressive and scout new territories. When they are in file and in column they are less of an issue if one approaches gently and doesn't create too much in the wa...

Of Armies and Agriculture

Sunrise over the Amazon: https://live.staticflickr.com/65535/50725122272_80fb503f85_b.jpg An army ant (Eciton burchelii) soldier has curved mandibles so large that it is physically incapable of grooming itself and relies on medium and minor caste workers to clean it. The jaws, with their backward fi...

The high key in the 3rd image works particularly well. The light's a bit harsh on some of the others, though shooting moving subjects in full sun is generally something I avoid. I can't say I have any recommendations on how one could shoot in that scenario unless you had a reflector/diffuser and a l...

You really captured the textures and framing well in the second and third shots. The 2nd in particular stands out.

Peruvian Amazon: Manu/Tambopata Part IX

Army ants (Eciton sp.) and a parasitic army ant-mimicking silverfish (Trichaletura manni). As many as 357 species have been associated with army ants, either as parasites or commensals. Some, like this obligate parasitic silverfish live within the colony itself and move with it: https://live.staticf...

Thanks Mark, Mike and Saul, much appreciated. Mike - For the fly, frog, mosquito and weevil I used the Canon Mpe and for the rest I used a 1.4xTC with 12mm extension tube on a Canon 100mm f/2.8L. The latter gives increased mag. and good compression of subject for background bokeh/details. For lighti...

Thanks Chris and Rik. I'll try to integrate any non-macros more into the narrative arc and limit them to 2 per set, and keep them for the final images.

The eggs hatch into nymph which have the overall morphological characteristics of the adults which are gradually ...
