New Charaxini Paper
by Cabintom » Mon Nov 27, 2023 5:54 am
The abstract:
The systematics of Charaxini is revised. The three historical genera are confirmed: Charaxes (Ochsenheimer, 1816);
Polyura (Billberg, 1820) and Euxanthe (Hübner, 1819). The genera Eriboea (Hübner, 1819) status rev.; Zingha
(Hemming, 1939) status rev.; Viridixes (Bouyer & Vingerhoedt, 2008) status rev. and Euxanthe subgenus
Hypomelaena (Aurivillius, 1898) status. rev. are reinstated. Three new genera are described: Laodice genus nov. with
the type species Papilio lycurgus (Fabricius, 1793); Setechin genus nov. with the type species Charaxes nichetes
(Grose-Smith, 1883) and Ydeali genus nov. with the type species Charaxes lydiae (Holland, 1917). A key to the nine
genera is provided.

Let's see now: I take the boxes of papered stuff out of the freezer, take the fumigant out of drawers, put it into the boxes, put the boxes on a shelf, and put the drawers in the freezer, and I'm good to go!Chris Grinter wrote: ↑Sun Nov 26, 2023 9:23 pmHaha yes just need the discipline to use the freezer for nothing other than pest management.jhyatt wrote: ↑Sun Nov 26, 2023 2:54 pmGot one, but it's too full of boxes of papered leps to hold any drawers!Chris Grinter wrote: ↑Sun Nov 26, 2023 6:07 am A chest freezer can fit drawers vertically, years ago I had one in a lab that could easily fit 6 at once.

Looking for "Käfer Mitteleuropas - Larven"
by Lucavs » Sun Nov 26, 2023 7:38 am
I'm looking for a while for the pages dedicated to the description and iconography of the larvae of species belonging to the genus Stephanopachys, (Bostrichidae). Can you help me? In Italy I have a lot of difficulty finding this source, where I believe they are well described.
A thousand thanks
Luca

Re: "Reptile Heaven" and "WildinsectUSA" = SCAM

I see they have "improved" their scam listing now some very rare species at high price (but affordable for the rarity) : https://reptileheaven.com/product/agria ... ournierae/ The real value of this pair would be at least $1,000.
I guess they steal pictures on the web of sold rarities and list them as if they have it. A simple google search about the rarity can lead you to their website.

Yep, it's a cholinesterase inhibitor. My bug room is a roughly 60' X 40' open basement, fairly well ventilated, and I don't spend huge amounts of time there. Still, it's a concern. Paradichlorobenzene also can produce neurological effects. PDCB is more volatile than dichlorvos and needs replacement much more often, so I've switched to dichlorvos. But I think I will follow Shuey in using smaller pieces than I have been.
It's a dilemma; I can see why big museums have gone over to watching and freezing when infestations occur. But without a really big freezer, that's impractical at home.

Re: Enough already, with the fake aberrations
by EdTomologist » Tue Nov 21, 2023 4:41 pm
As someone who wrote their thesis on the topic of wing development signaling, tungstate is mainly effective for nymphalids and certain groups of butterflies. It’s less toxic than other compounds and easily accessible. This makes it a good and easy option for producing aberrations.
There are in reality numerous compounds that induce aberrations through different mechanisms. Some of them mimic stress responses that result in darker wings. It’s a common immune response in insects to produce melanin.
There are also variable patterns that can be induced depending on the stage of injection.
I have been working with a new compound that can actually lighten the wings instead of darken them.
Given that my work is still to be published I don’t want to reveal too much. I also do have a concern regarding individuals using my work to sell man made aberrations but I believe it’s more important to have knowledge freely accessible.
I should also note that unlike tungstate where the mechanism of action (how it works) is unknown, a lot of other compounds we know exactly how they act. The main difference between compounds is their toxicity, the cost, and the difficulty in acquiring the compounds (must have scientific institutional purchase accounts).
Below is an artificial aberration from my research a while back plus link to other pictures.

Of course the usable lifetime may vary from drawer to drawer, depending on the rate of air exchange inside the particular drawer. I renewed all of mine about 1 year ago; I guess I'll let them go at least another year, or 2 or 3, unless I find an infestation... and I'll replace it in any drawers where I notice an unusually pale chunk of dichlorvos strip. I suspect there's no valid general answer to my original question.
