Never seen L. populi flying ! In France, this is a very local butterfly and you must be at the right place at the right moment (the lep flies about a week only). These locations are pretty far from my home and the butterfly emerges when I have a lot of professional work ! Same thing with P. mnemosyne : it flies when I must stand at the University ! I have looked for L. populi several times in large woods in NE France. It can be very common - there are times when I've seen 30+ males on the ground together, but as others have said, the flight season is very short - not much more than a week. It also varies a lot from year to year but is usually around mid-June, however, this year it could even have been in May. A. ilia starts flying in the same woods towards the end of the populi flight season and A. iris about a week later. I've seen these two species there in their hundreds. Bob

Thanos, kaly mera sas ! "it consists of a long fishing stick,made of hard but light plastic(easy and practical to handle when the stick is spread and you reach the butterfly high on the tree to catch it),which has 7-8 pieces which are the one inside the other,and when you see the butterfly sitting high on a tree,you don't spend time" I have a net of this kind of Czech origin, ie, telescopic say. It should have a range of 7 to 8 meters. But - Folded, it measures 1.80 m: impractical to put in his suitcase during a trip (especially in a country where hunting butterfly is prohibited ) and to move the border police. - It is quite heavy and unwieldy; - And, above all, as written by Nomihoudai, the net carbon breaks too easily. Therefore, the last time I took it for a trip (in Arfak Mountains in Papua), I used to hang my mosquito net only and not to catch Ornithopters! ;D ;D To-day : rain and rain, showers and showers : no butterfly flying ! It will compensate with snails or frogs ! Attachments:

To bobw ! "I have looked for L. populi several times in large woods in NE France. It can be very common - there are times when I've seen 30+ males on the ground together, but as others have said, the flight season is very short - not much more than a week." As far I know (we had one month ago a large talking on the matter inside our Lepidopterists Association), Limenitis populi is not endangered in France and can actually be very common where it is located. Bobw rightly evokes the forests of France from the NE. More generally, the species is found throughout the East of France in the contact zone between the plains and mountains. According to latest reports, it progresses in recent years to the South (Southern Alps and foothills). So, in July 2008, Limenitis populi had been observed for the first time inside the "Jardin des Papillons" de Digne (Alpes de Haute Provence). See : www.proserpine.org/papillons.php As soon as I reached the age of retirement, I'll settle down in June at the foot of the Vosges or the Jura or the Alps! Above picture : a forest path where fly A. iris and A. ilia. Attachments:

According Cidinha (the photographer), the portuguese name of the fish is : peixe dourado-cachorro Looking on Google, I found : Acestrorhynchus pantaneiro : "A long-bodied fish, reddish in color, an agile swimmer, it is found on the surface of still water such as lagoons and dead arms of rivers. It feeds on other fish and small freshwater shrimp and reproduces in the rivers of the Pantanal plain at flood time. " from : www.cpap.embrapa.br/agencia/peixes/Peixe010cachorro.htmI can't tell more ! JMG

I know it! I used to keep tropical fish and it is one we call the Pike Characin, only to be kept in an aquarium on its own. It will eat anything and bite our finger to if you are not careful. It looked a lot bigger in your photo as these usually only get to about 15cms. in captivity, the information I found says they get up to 30 cms in the wild though. Thanks for the info J-M!

I presume that I made a liitle error (I'm very ignorant about fishes) ! Acestrorhynchus pantaneiro seems to be restricted to the Pantanal area. In amazonian rivers, the species is Acestrorhynchus microlepis. According this australian website : www.dpi.qld.gov.au/28_13111.htmAcestrorhynchus microlepis is a true terrorist ! Let read the following text : "This fish is declared noxious in Queensland. It is illegal to possess, rear, breed, sell or buy pike characin, live or dead, without a permit. It is an offence to release pike characin into Queensland waterways or use them as bait, live or dead. Penalties of up to $200,000 apply. Pike characin are not known to be in Australia, however if they are found within Queensland they should be immediately reported to Fisheries Queensland. Scientific name : Acestrorhynchus microlepisDescription * small predatory species reaching a maximum of 26 cm * an ambush predator * has a torpedo-shaped body * small to medium-sized eyes * large mouth full of sharp teeth * streamlined fins which can be contracted for maximum speed * tail fin is large and forked * a silver-green on top fading to white on the belly * has a black spot behind the operculum and one on the tail. Distribution * native to South America, in particular the Amazon and Orinoco River basins and rivers of Guyanam Suriname and French Guiana. Habitat * commonly found in clear water streams, rivers and lagoons * prefers slower flowing waterways, usually off-channel habitats of white-water rivers * a tropical species preferring temperatures 18-28°C. Diet * a voracious predator of small fish but may also consume insects when vertebrates are scarce. " Attachments:

Dear Jean-Marc,kali mera sas ! Sorry,I made a mistake above.My tall nets(the telescopic fishing sticks at the edge of the last piece of which I have adapted the net) are carbonated,not plastic ! This is why they are so flexible and light and that never were broken during my collecting. These telescopic carbonated fishing sticks are quite expensive(more than 100 euro each),but they worth,as you can reach a butterfly up to 10 meters on a tree(!),they never break,and are light ! I have adapted a wide net at the edge of these sticks,as mentioned above,and I've collected great specimens high on the trees,like females of L.populi and A.iris,Thecla betulae etc,even I have cought with them big Lucanus cervus males which were high on the trunks of tall Quercus trees !

First I took some pictures and, secondly, I took the butterfly. It will be spread this evening ! Same morning (June 21th), first apparition of Colias alfacariensis, Issoria lathonia. Very fresh A. urticae, Inachis io and so on. I believe they emerge this morning after this long rainy week. Attachments:
