do you have the original paper ?
- strange to compare pyrale to actias as blank (not exactly the same prey as one is quite bigger than the other, and pyralidae have tympanal organs missing in Saturniidae) - one have to see one time an Eudaemonia flying. It is an extremely fast flier possessing a kind of helicoidal flight (not the same as Argema, more erratic) - must be verified in the paper but the logic is to use a pairs of predator / prey existing in nature.
I completely agree that tails are a response to predation. It increases "the volume" occupied by the lepido flying with a big part inoccupied (espacially in species such as eudaemonia and his helicoidal flight). Sure that the attack of the bird / bat is more inefficient. No needs of a computer to understand this.
A complementary method may be to count injures made on natural specimens (with an estimation grid of kinds of attacks making these injures)

Where do those come from? I've never seen anything like that here in Thailand. Adam. they are not visible as being kept in ant nest. it is necessar to look Inside nest to see or catch them (honey reserve)

This si a very partisan debate. A group is not another and a single specimen is not another. A specimen of O. goliath seems sufficient to describe it as a new species while describing a specimen in some Parnassius or Colias seems very hazardous. DNA is it's The Truth just a tool like others. Thousands Charaxes have been barcoded (nearly all African species). It gave nice resuts in some groups (with still unpublished results) and in other groups it gave nothing (such as the eudoxus and jasius group). The black complex will remain difficult even with DNA analysis. Description of pythodorus ventersi seems obvious while those of amandae should have been more careful (it is of a complex of species very variable with some doubtfull descriptions). Of coures, I would have described Charaxes lydiae or fournierae on one specimen The common sense will remain the best tool

WOW So impressive ! I don't know why but there seem to be a predisposition for Cymothoe to do gynandro. I have seen many for sale. some explications - the great sexual dimorphism that makes the gynandro easily recognisable in the field (also the flight is unsual because of asymetry) - the "search pattern" of the local hunters that are looking for them - the incredible great number of butterflies caught in CAR
there are not only many Cymothoe gynandro, also others such as Charaxes, Papilio (at least 6 gynandro of antimachus and zalmoxis were caught there)

Thierry, Great to see you here. Do you remember if there was significant difference in colour on the underside of true female zalmoxis? You sent me an upperside photo of the one you had some years ago, but I never did get to see the underside. Adam. I can't remember but what is sure is that the species is quite variable in wing shape and color pattren (R and V). The confusion is easily possible.
any way, this is buying a pig in a poke !
I know Alain (he is Belgian and was not far from here). He is not entomologist. He is usually honnest but because he is not entomologist, there are things he can't verify.

Thanks a lot Thierry for these precisions. Following the discussion here, I subscribed to Lambillionea and sent a paypal payment. Could you kindly confirm me that you received it ? I wrote to Lambillionea mail but didn't receive any answer. My email might have arrived in the spam box ? when ? we had a great problem with the yahoo email (I change it recently in an Hotmail account)

I just discover the forum. i have the same feeling as Adam bouyt the abdomen. Strange also that a guy selling a such rarity don't make some verifications, photos (espacially dorsal), etc... For a such affair, the doubt is not admissible.

Is "Entomologia Africana" still published ? Yes Olivier it is still published, and it is the same president as Lambillionea. Originally, it was a competitor of Lambillionea, and I thought that with a common president it would become a joined publication, but so far, it is not the case ! A+, Michel Michel, I am quite surprised that you wrote lambillionea being competitor of Soc. ent. afr. (Entomologia Africana revue). We have yet spoke together about that in the past. This is untrue : Soc. ent. afr. has been created with the great support of the Lambilllionea president of the moment, the late Jacques Hecq. There were never a competition spirit, just the need to create something specifically African and limited to coleo and lepido (politic of Lambillionea was multigroup, any language and worlwide). Hecq published some papers in Ent. Afr. and authors of Ent. afr. published in Lambillionea. Entomologia africana is the revue of "Société d'entomologie africaine asbl" (site : www.entomoafricana.org/), it is published twice a year. Lambillionea is the revue of "Union des entomologistes belges asbl" (site : www.lambillionea.haisoft.be/). Some people are common to these 2 Belgian societies. It is published three times in the years.
