rarity is just relied to appropriate habitat / season and collecting method. knowing behaviour and foodplant is useful !
If a species is (become) really rare, it can't survive !!!!!

Yes,I agree with africaone in this. Example from my country: An old collector from Greece( Mr Koutroubas - wollastoni knows him,they collected Delias together),although has been collecting here Limenitis populi for much more years than me,he has caught only 1 female(and this was fallen down to the forest road,hit by a strong rain!),among many males in his collection,and I'm not sure if he has seen all these years more than 2-3 females flying(btw he tried traps with rotten fruits,but no female). I have collected more than 10 females,cause I found a more appropriate habitat(with Populus tremula trees - the larval foodplant) and spotted also the right season for the females.(Also I've observed their behaviour at that habitat,and know that the best times in the day to see them is in the morning and in mid-afternoon,when they come down to the forest road from the tree tops, or fly more close to the ground and lay eggs/rest at lower heights on the Populus trees and with a tall net you can catch them there).
But also, some (sub)species,occur in much lower numbers than others* or their females are much more elusive than others.
*for example the population of ssp.atrides of Parnassius apollo here is much lower than the one of the ssp.graecus,and this doesn't have to do with the season. Another example,the female Papilio antimachus,I believe that both is extremely elusive(high on the trees' canopy) and occurs in much lower numbers than the males(and than the females of most Rhopalocera species),so to be known from only a handful of specimens worldwide,although the localities/habitats of this species in Africa are known(or is it so difficult to spot the right season for the female of this species..?).And although human can't find these few females,some of the many males find them and so the species survive.

Apologies... I was going to try and make my picture larger and deleted it... Something then wouldn't let me re-insert it...Then I got in a spin and decided to erase all reference to it...A plethora of 'senior moments' I'm afraid... Will put it back as it was...   Barry caption should read: Rarely offered Delias in my collection: A trio (male,male,female) of Delias subviridis from Manusela, Ceram Island and a trio of Delias dorylaea from Mount Gede in Western Java... |

If you have attached a picture to a post and then edit the post and want to change the picture etc. it doesn't work anymore, you have to delete the post and write a new one, that usually is not a problem as long as people did not reply yet, if they did you can't insert your post anymore at the specific place.
Thx for this new version of that nice picture, the arrangement of specimen does remind me of "The butterflies of Russia".
And don't worry about the topic looking strange now because your post got deleted. Thanos reply after your post makes, even without your post, more sense than his last one he wrote now here. ( Who cares in this topic about him catching Limenitis populi ? Are you serious ? ... )

Let's feed again this topic : Delias cumanau male, Foja Mounts, Bog Camp, 1650m, West Papua ,2008 ,"Lost World Expedition, Coll. PequinYou may have heard of the so-called "Lost World Expedition" where new species of mammals, insects and so on have been discovered in a very remoted area of West Papua, the Foja Mountains. Delias cumanau was discovered during this expedition. This is one of the 5 discovered specimens during 2 expeditions. I am very lucky to have it in my collection. Attachments:

 I do not know the price of Delias on the market! To answer the question posed by Thanos: why are they inexpensive (although they are very localized, fly high and fast, etc.). I reply with an anecdote in Arfak: A local dealer (Olivier knows him well, I think) offered Delias meeki or D. albertisi as gift to the buyer of a couple of O. goliath samson! Indeed, in this area of the Arfak, O. goliath is certainly much more common than D. meeki! Every day I saw several goliath, while we (we were almost a dozen on-site, including the "old greek collector" evoked by Thanos) have seen (and captured) a single D. meeki and one or two (not more) D. albertisi. Globally, on the market for butterflies, there are many buyers for O. Goliath and little demand for D. meeki. What is not without surprise me: the Delias, with Riodnidae Neotropical, are among the most extraordinary butterflies with a variety of shapes and designs really fantastic. I fully understand that one can become a " Delias lover" or a " Delias addict". I have a small collection of Delias (practically only butterflies I caught myself) are among my favorite butterflies! As attached picture, D. albertisi from the excellent Leslie Day's website : www.delias-butterflies.co.uk/Attachments:

About Delias prices. Common one are cheap, rare one are expensive. D. niepelti (meeki doesn't fly in Arfak) and albertisi are common species. We are talking about a genus with 300 species. I won't say all Papilio are cheap because Papilio machaon is cheap. I have seen some Delias offered upon 1000 € (messalina, Foya specimens, orphne rare ssp, brandti female, hikarui female ...) + some Delias have been found in only one specimen during centuries (takashii, orphne tahaanica...). Prices for rare Delias are very high because Japanese collectors are ready to pay crazy prices for them.  |

In all my 400+ specimens, I only have one lonely Delias and that is Delias Sanaca Sanaca.
The picture is too big for InsectNet's lousy attachment agreement. Why is it only I seem to be having problems with this? I constantly see photos of much bigger subjects than Delias being uploaded. Why can't my butterflies even make it on? I've got so much to share!
1,024KB as a limit is just too ridiculously low!!

resize them ?? 1024 kB is huge for a free forum software...anyway, open picture in MS paint if you got windows and then resize it to 800 pixels length or somethign like that,... then you only have about 150kB and still lots of details.
