Re: How Genetic studies reveal new relationships, species

Thanks Adam. "Smaller difference in COI". Noting the other factors- range, flight period, etc. how the heck then would one determine Sp vs SSP considering COI? If we use 2% as a safe range for species (noting that many are now less than that), what might be the difference for a ssp? Must ...

Re: Fumigant Lifetime

[quote=Chuck post_id=8523 time=1701093488 user_id=100 It's my suggestion to find a way to freeze drawers, always keep humidity under 50%, and avoid fumigants. This, of course, is not always possible, but for those who do have the space (yes, you do John) a freezer (or second freezer) is the way to g...

Re: Fumigant Lifetime

A chest freezer can fit drawers vertically, years ago I had one in a lab that could easily fit 6 at once. Pretty cheap to purchase and run. Got one, but it's too full of boxes of papered leps to hold any drawers! jh Haha yes just need the discipline to use the freezer for nothing other than pest ma...

Re: Fumigant Lifetime

The other thing to ponder, this stuff is not good for you. It can cause neurological damage. My bug room is pretty small, so I use it as sparingly as possible. John 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...

Re: Fumigant Lifetime

In some of my drawers I haven’t change them since I started using these in 2015-16. They are pale yellow but so far no pests, I’m not sure if they still do work or I have no pest in my room. Of course the usable lifetime may vary from drawer to drawer, depending on the rate of air exchange inside t...

Fumigant Lifetime

I use dichlorvos strips ("No-pest strips") in my lep collection. I cut the large yellow slabs one can purchase into roughly 1/2" squares and pin one in each Cornell drawer. This seems to work well - I've had no infestations since I started using this material years and years ago. But ...

Re: Papilio erskinei

Very good post, Chuck! And I do like the use of "Luminaries"... although somehow I still like the older usage of "Virtuosi" for people like Tennent, Cotton, Sperling, et al.

Cheers,

Re: Damn frogs, toads, lizards too....

I get more varmints in my bait traps than in pheromone or light traps. Hornets certainly can devastate a nice catch!

A friend of mine used to sometimes hang a warning label on his traps with words to the effect: "African Killer Bee Research Trap -- Danger -- Keep Away!'

Re: Damn frogs, toads, lizards too....

Never had that problem here in the southern Appalachians, but more than once I've left a moth sheet running all night, only to find in the early morning that all the moths were gone from the lower 12-18" of the sheet... and a pile of raccoon poop nearby!

Re: What do Hesperidologists dream of?

I do truly love collecting skippers, but I've never dreamed about them that I can remember. The only butterfly dream I can vividly recall is one of being on a small island, apparently in the New Georgia group, and watching a male O. victoriae rubianus flying out of reach overhead, just above the edg...

Chuck,

No, don't think I'd go in 2024. Got too many other places to hit, rather than return to one I've seen before. Thanks anyway!

Re: Every year I say I'm going to AZ "next year"

Chuck, Been there, done that. Many years ago a group of 4 or 5 of us spent a long week collecting all over SE AZ during that period. Two drove out in a van with the generator, light traps, batteries, bait, etc; the rest of us flew to Phoenix and rented cars. We stayed in motels some, and rented a ca...

Re: Shipping dilemma

I just went to the central PO in town and mailed my parcel for less than half what the original local PO clerk told me was the cheapest way. I reboxed it in a larger (9X6X6) box, which more than doubled the weight, but it avoided a small-box surcharge and some risk of loss. The clerk I used today ad...

Many thanks, Kevin and Chuck! I'm apparently dealing with a less-than-knowledgable clerk. USPS website says there's a "First Class International Package" class for small light parcels; service to my target country runs about $15-19. And yes, my package is too small to fit the designated li...

Shipping dilemma

Has anyone discovered a way to ship small (say 3X4X3 inches), light (say 2-3 oz) parcels overseas without incurring the absurd cost of using the US Postal Service? A box of this description to a western European country now cost US$ 58 to ship, I was just told by the P.O. clerk. As recently as a yea...

Re: 53 feet (16 meters) above ground

Vernon, Thanks you very much for your very informative reply. I see now why you didn't try hoisting your bait traps to the canopy! I've seen that done with lightweight traps in the tropics, and wondered if anyone had tried it in the US. Did you ever have problems with your large volume of bait getti...

Re: 53 feet (16 meters) above ground

Vernon, Have you ever found that bait traps placed in the canopy attract different species consistently compared to those near ground level?
Tks,

Re: Catocala 2022

Vernon, how much did having lengthy series of specimens contribute to your recognition of potential new species? For me, if I have one specimen that looks a bit different, I'd just write it off as a variant/ form. If I have twenty of something that looks consistently different, it makes me ask why....

Re: Odds & Ends

I must admit to having a few catch-all drawers myself. They're mostly neotropical Lycaenids or small moths that are awaiting determination... some for several years!
