Limenitis chrysalides
by lamprima2 » Fri Mar 29, 2024 3:09 am
function of a flipper-like outgrowth on the dorsal side of
Limenitis lorquini chrysalis? It is present in other
Limenitis species as well.

Yes, it's sad to now look back and see how so many species are extirpated from the lands they once occupied. I did find it interesting that in the early 20th century they reported (as you cited) species expanding in range, and apparently quickly.

Butterflies of Virginia, Clark & Clark 1951
by Chuck » Wed Mar 27, 2024 5:53 pm
I pulled this book out to research something, and got caught reading it. I'd forgotten just how wonderfully chock full it is with information. It's not just about Virginia's butterflies- it goes into extensive observations by Mr. and Mrs. Clark and other researchers, correlations with weather patterns, and goes well into other states. Unlike most books on identification (from Golden Nature to Opler or Scott) this one goes into details...it's more like a very thorough field notes.
Though many hypotheses and taxonomic "facts" have been changed in the 70 years since publication, it is astonishing the number of questions raised, generally in the form of observations that don't quite form a conclusion, that remain unanswered today. And being a snapshot of the time, focused on the early 20th century, some observations now may be relevant, such as one taxon that had apparently been moving north- an early harbinger of climate change?
It's an astonishing read, from end to end, because it's not just a book about butterflies, it's a story, a true story. Clearly, the author didn't intend it to be that way, but with all the name dropping, period observations, and data it has become a story.
Unfortunately, I could not find a copy available online to purchase. But you may want to keep your eyes open.

Selection of taxa for the study was based on available taxonomic
information on the Charaxes species-group (Ackery et al.,
1995; Larsen, 2005; Williams, 2008). As ingroups, the exemplar
species were selected such that they represented all known ‘informal’
species-groups of Charaxes in Africa (a total of 125 specimens
of 83 species). We also included as ingroups all known species of
the two Charaxinae genera (Euxanthe and Palla) in Africa, three of
ca. 30 Oriental Charaxes and two exemplar species of Polyura.

Oh I'm not worried, you can't take money with you, but on second thoughts , cant take butterflies eitherwollastoni wrote: ↑Mon Mar 25, 2024 10:08 am There is a "Make an offer" button. Nobody will pay so much for elephenor, don't worry.

Interesting - thanks; I've occasionally seen these moths over the years, and just assumed that they were a species of Catocala.Trehopr1 wrote: ↑Mon Mar 25, 2024 11:52 pm There is a species of moth which has evolved the cryptic
forewing coloration of underwing moths (Catocala) along
with the "flash coloration" aspect of the hindwings.
It is commonly known as the Locust Underwing (Euparthenos
nubilis) as its larval host is black locust AND it is the only
member of its genus in America north of Mexico...

Euparthenos nubilis -- the false underwing.
by Trehopr1 » Mon Mar 25, 2024 11:52 pm
forewing coloration of underwing moths (Catocala) along
with the "flash coloration" aspect of the hindwings.
It is commonly known as the Locust Underwing (Euparthenos
nubilis) as its larval host is black locust AND it is the only
member of its genus in America north of Mexico.
Much like (true) underwings it is fond of fermenting fruit, fruit
baits, and mercury vapor lights. So, it can be an occasional or
even common visitor whenever/wherever someone seeks
catocala specimens.
The photo below features an adult (female) at the top
whilst a specimen of our Oldwife Underwing (C. paleogama)
is situated below.
It is easy to see how this species is often initially mistaken
for a true catocala by those first initiated with the method
of "sugaring for moths". It is also a wonderful example of
how evolutionary success in nature carries across a broad
spectrum of species and genera.

Aduse-Poku seems to not recognise C. Lydiae as,a member of Charaxini in his system of classification.
Thierry Bouyer has given Lydiae a separate monospecific genus, stating it as unique in regards to all other Charaxini members.
Can one assume then that Aduse-Poku didn't consider Lydiae as a member of Charaxini or, just missed including it ?????

well im afraid I'm not going to follow either of these ruleswollastoni wrote: ↑Mon Mar 25, 2024 10:05 am There are 2 important rules in taxonomy :
#1 : you have to follow the latest publication. So in this case Bouyer 2023. (We now have scientific techniques like DNA analysis we didn't have in 2009).
#2 : InsectNet members are always right, so once again, you have to follow Bouyer 2023 (@africaone on this forum).

Yes, the potential new one is sympatric with both spatulata and 6 other species that cannot be separated by wing pattern alone. The biggest wing pattern element that differs between species is tail length! And most of these species have at best, subtlety different genetalia (see below). The potential new species is actually easier to separate than most of the others. All four of the species below are sympatric with the potential new one.
