Please could you divert the post of Vanessa atalanta migration 2024 to separate thread. Everyone could report here.

We have here on the north side of the Lake Ontario also unusual numbers of V.atalanta. I am not surprised. Clearly they are coming from "south." The question is: why in such numbers? I suspect that warmer weather thru North America this winter cause higher survival rate, also very mild te...

Last week, before it snowed, there was an unusual number of V. atlanta around. It warmed up a bit three days ago, albeit with rain. Today it's 64F and sunny. There are hundreds of atlanta, everywhere. Most are flying fast, I've only observed one alight. They are absolutely beat. So either there was...

I suppose if it wouldn’t be AI there be already response to all the comments have been posted if a person is expecting some answers.

I will be travelling in mid June (peak season) to Alberta’s Rocky Mountains from Banff to Waterton Lakes NP.
Does anyone know reliable location for Anthocharis julia sulphuris ?

My advice is if you don’t use local organizers like Amazon insects in Peru or Amazon Lodge in French Guiana who will take care of you right at the airport, rent the car at the airport of your destination. You’ll feel comfortable, safe and have shelter just in case you end up having no place to sleep...

I can only agree with John’s posts!
If you don’t go collecting in tropics you don’t live your life.

Today April 10 another warm day and I saw Vanessa atalanta, this species can not overwinter here in south Ontario and it migrates from south usually at the end of spring. I have never seen them here so early, it could be a good year for migrating species as the warmer than normal weather maybe allow...

Today April 7 I saw first P.rapae here in South/west Toronto. The spring is officially here and it is about two weeks earlier as we had very mild winter this year.

It is indeed, thank you so much for the link

Does anyone know current systematic of this species?
Also if anyone knows good locality to collect it around eastern slope of Rocky Mountains south of Calgary.
As far as my research there should be A.stella inhabit some areas.

I have seen D.plexippus in Costa Rica and Dominican Republic. It does not occur in Thailand or Laos, at least not yet, most of subspecies other than N.American nominate don’t migrate.

I would also relaxed and spread the specimens. This is the only safe metod. I did it to my entire collection about six years ago changing all black and some old steel pins to proper size stainless steel and included all laser print labels. It took me several months as there was about 1000 specimens ...

Müllerian mimicry

Very nice species. I have never find it in Northern Thailand which it may not occur there.
I would say it tries to mimic Byasa polyeuctes or dasarada.
Few hundred thousand of years and it will get there.

Indeed, it is difficult species to net and most of the time they are in A2 condition so to find nice examples is not an easy task even that the species is quite common in forested areas along the streams.

What is the main advantage of plastazote, over something such as foamcore? Do pins not leave visible holes in plastazote, if removed? It also grips the pin quite well, despite the fact that the pin is very easy to insert. Just a wonderful material in every way, including appearance - it has no refl...

I use Japanese green net and paradox khaki net. They are not so visible from far and not asking for trouble by annoying people. I used to use them for many years now and when I try my old white net I couldn’t locate the catch in it. Somehow white colour blind me and can’t really see thru well. Keep ...

It is Calinaga species and if it’s from Vietnam it could be Calinaga buddha. All species of this Genus look similar.

Yes! Indeed, it sounds wonderful as long as we will have enough energy and good health. It could be a great way to finish the journey here.
