You can buy syringes and high percentage ethanol in any pharmacy.
I haven't used killing agents on butterflies since years. I only use it for moths.
For butterflies all you need to do is to hold them between thumb and index finger when they are in your net and press firmly on their thorax and they will stop moving.
In Germany the common species are not protected (around 25), but the others are. In France only a few are protected. Switzerland and France are the friendliest countries to collectors.

“ Nomenclature is not a science. It is like an accounting” Huh?
Taxonomy - In biology, taxonomy (from Ancient Greek τάξις (taxis) 'arrangement', and -νομία (-nomia) 'method') is the scientific study of naming, defining (circumscribing) and classifying groups of biological organisms based on shared characteristics.
Nomenclature - (UK: /nəˈmɛŋkləˌtʃər/, US: /ˈnoʊmənˌkleɪtʃər/) is a system of names or terms, or the rules for forming these terms in a particular field of arts or sciences. The principles of naming vary from the relatively informal conventions of everyday speech to the internationally agreed principles, rules and recommendations that govern the formation and use of the specialist terms used in scientific and any other disciplines.
He isn't wrong in what he is saying there. He means that nomenclature is a set of rules and conventions rather than a reproducible science.

You label it with the data that it comes with. If you purchase specimen with or without labels is up to you. Still, most stuff comes with basic data at least.

I got one large cabinet and a smaller cabinet. The large cabinet was brought to me by the owner of the company himself. I was living in South Germany at that time and he was on his way to Switzerland to furnish one of the larger museums. Many museums in Europe have become customers with Paradox Company which speaks for their quality and the good price. In any case, I assume you live in the UK. It should still be possible to find an affordable trucking company that can handle the delivery (I assume something around $100, but don't nail me down on that number). I also had a smaller cabinet that was shipped by trucking company to Luxembourg. I particularly liked the open face of the smaller black cabinet. Many color combinations are possible. I always went for very dark cabinet and light drawers.

You got me there Adam. I quoted from a book that has artwork with this same beetle. I might not have seen the 'i' due to a parenthesis after it, or the autocorrect on my phone turned it into a correct Japanese spelling. It's Chrysochroa fulminans nishiyamai. Also, the island in the book is Pulau Simuk.

Make sure to get the right one, because the nominate Chrysochroa fulminans is all green.

Most likely Chrysochroa fulminans nishiyama from Pulau, Indonesia. How do I know that? They are a common supply in artwork.

The prices were visible just after it ended. But a day later the web catalogue was not accessible anymore.

I saw some of the prices live. There was a smaller collection by a Danish collector that went for 2300€ for 20 drawers. It was a nice collection as he had pinned some specimen sideways to show the underside. I was amazed by the prices for some of the Arctiinae (around 1000€).

Tragic news indeed. He was a very active contributor to the forum some years ago.
In 2017, I very briefly visited him before heading to the LepSoc meeting. That was all way before his diagnosis. I drove about 6h from Urbana-Champaign to his place. He had one of the best private collections I had ever seen. I was only able to see select parts of the collection as it was way too vast. RIP Danny.

Do you have other pictures? This is really hard to tell from this pic.
Thanks for the donation.

Oaks have taken over in the US and shaped into any imaginable shape. The US has 160 of the 360 known species. Texas has 60 of them. My favorite is Quercus virginiana as they grow to an impressive size and their branches grow in an erratic way.

The main thing I have learned this year is how bad people are at making and reading statistics. When it has been studied the question is when, where, and how. What I want to say, if the study is from the 1970s, you can most likely trash it as the authors wouldn't even have been able to imagine the current state of the global world with its number of inhabitants and the amount of cars going around.

I'm not buying global warming, not at this scale; many species range across multiple zones and massive geographic areas, and many are readily able to exploit a warmer and thus expanding range (e.g., perhaps P cresphontes expansion northward.) Maybe it's ethanol fuel, maybe it's solar radiation. I have NO idea, not that I can in the least demonstrate. I quickly wanted to comment on this. First, I do not know what they wrote about the effects of global warming in the article as I do not buy any magazines.
Anyway, the effects of global warming in species distributions can be seen. The only work I published in Lepidoptera was the first occurrence of Agrotis puta in my country of origin (Luxembourg, central Europe). It has two eco-types, one of which is heat loving and of Mediterranean origin. Furthermore, in the 00's we started to see Brenthis daphne which is of Mediterranean origin and was expanding through the Rhine valley to Luxembourg. The other species of Rhopalocera which we started to discover starting in the 10's was Everes argiades, another species that comes from drier and hotter areas. Macdunnoughia confusa is a Plusiinae that was a regular visitor at my light traps, I read that 100 years ago it wouldn't exist north of the Alps.
But there is two things to a species, distribution and total numbers. And I say that Chuck is right with his doubts on the effects of global warming on total numbers, because as he stated species are able to expand their ranges, and as the observations show, those that can, do.
Monocultures, and cars will be the ones to blame. From a species' viewpoint our agricultural fields are impassable wastelands void of food sources and adequate shelter. Nature can only thrive with a network of various species, and this can only be done in undisturbed places. The other thing is that a network of roads is spanning large parts of the globe and cars are extremely good at smashing small insects. I have a small park nearby which is somewhat undisturbed (saw many snakes there and a bobcat) which has a walking trail. On the walking trail you would see piles of smashed bugs that have been trampled on or run over by bikes. A species can only survive in that area if their reproduction rate is larger than the losses incurred on that trail (unfortunately many species like to sun bask and gather on the trail).
I also do wonder about the effects of micro pollutants and chemicals on the fertility rate of some insects. But, we will never know as the general public will not fund or care about such a study. Furthermore, the quantities at play are difficult to assess and measure. So the study will not be conclusive.
I am a professional scientist and sufficiently trained in math if that eases the startled minds of some readers.
