|There are about 13-16 species in the genus OCARIA. This small species is distributed from Panama to Bolivia. This Lycaenid flies on hilltops and usually perch at 1mt above the ground where display territorial behaviour.|
Many butterflies and other insects fly toward hilltops and mountaintops in order to find a mate, where the efficiency of sexual encounters is increased as the mating area is reduced . This phenomenon, known as “hilltopping”, is somewhat similar to leks established by some birds, beetles and flies and it has been extensively studied by several authors.
Hilltops can have a small area relative to the number of species which make use of them, suggesting daily or seasonal activity patterns in taxa occurrence and abundance.
On Neotropical hilltops species richness can be very high, the abundance of single species can be high, the area in which individuals fly is small and individuals enter in direct interference when they carry out courtship and territorial activities. Moreover, some uncommon species are easily found in those sites. Though, hilltopping has been noted in several families of Lepidoptera, probably Lycaenidae is the one that possesses higher abundance in neotropical mountains. Prieto and Dahners (2006) have registered more than 80 species of Eumaeini (Lycaenidae) that regularly or sporadically visit San Antonio’s hilltop (2.200m.a.s.l) in the “western cordillera” of the Colombian Andes, and more than 90 Eumaeini species in another hilltop located at 1750m above sea level.

My earlier visit to your gallery was quick and short but this time, i have had a good round around and i understand you are a specialist in this field and what a nice collection you have!
I'm quite a novice in photography,but i decided to share with you what i know after reading your intro.Regarding the quality of pictures, there is a certain amount of difficulty which many of those using Point and Shoot cameras face.I use one, so i'm quite used to this situation. And this also adds to our limitations many a times in getting a fine picture.But there are also certain post processing softwares that can help you better your images.Like you could use 'Neatimage' to clean up a certain amount of noise on the shot and further use 'Photofiltre' to further to make the image a finer once changing levels of sharpness, colours etc. Both are freewares you can downoad from the internet.Play around with the camera and the softwares and I m sure you will be producing some of the finest butterfly images on TN.You already have a great gallery and one of the finest collections of butterflies in TN.
This is a nice image you present, with the details of the b-fly standing out excellently.Very fine PoV and colours.I do not know whether you used a software to sharpen it already.But i have tried a workshop using Neatimage to reduce the noise and also for my own learning...Hope you wont mind.

a perfect picture of the beautiful Lycaenide - perhaps a little dark (in my opinion).
Sharpness and visible details are amazing. A very nice and valuable introduction to that species.
Best wishes, Peter
P.S. Can you give the full reference for the 'Prieto'-paper?

This is a very good close-up of the butterfly showing wings pattern in great detail. You have used so well the soft light rendering excelent colors. The red eyes from the backwings look great.
Thank you for sharing,
