Shipping dilemma
by jhyatt » Thu Sep 28, 2023 4:52 pm
I have to guess that commercial couriers (DHL, UPS, FedEx etc) are even more expensive. I must admit that I'm a bit in shock, not having sent any bugs overseas in a couple or three years. Trading isn't worth the cost of shipping any more, I fear.

Re: Mould removal from specimens

It would be helpful if you explained what sort of specimens you have mould problems with. Different techniques can be used for Lepidoptera and Coleoptera.
Also there are different types of mould, such as one that looks like a white sheet, or others which are not so obvious, but produce small brown spores all over the infested area.
Adam.
PS. I just realised you wrote this in the Lepidoptera forum, so you must be referring to mould on butterflies or moths. The type of mould would be useful to know, and also are the specimens spread or papered? Adding a photo may be helpful too.
Ethyl acetate may kill the mould and stop it from spreading further, but one of the best preventative actions is to completely dry the specimens. That won't remove sheet or thread mould, and if spores are present they should ALL be removed with a soft paint brush.

I captured amazing amounts of butterflies, hawkmoths, catocala, on and on using these traps. Sometimes we would empty the live capture traps in the early morning hours (while the captures were still inactive from the night time), and by mid afternoon there would be 300+ catocala in each trap. Too bad my methods were so labor and man-hour intensive. Attached is a non-published blurb about our bait recipe. ALWAYS AVOID USING HONEY IN YOUR BAIT>

Did you ever have problems with your large volume of bait getting "over-fermented" - i.e., generating a lot of vinegar - in the trap, and stop attracting leps? I've occasionally had that happen, but them my bait prep methods have never been as systematic as yours.... I keep varying the receipt.
I buy overripe bananas when I find them on sale, peel them, and freeze them for later use. I've never tried making complete bait, letting it start to ferment, and then freezing it for later use. Might that work?
I've had occasional trouble with store-bought apples. Some of them never seemed to rot, even with sugar and beer added. I suspect the trees are grown with a systemic fungicide which gets into the fruit, but I don't really know. I now stick with homegrown apples.
Regards,

The bait works best with over ripe fruit and even better using cane-sugars and yet better using alcohol (beer) which has yeast. Saying that 'NEVER EVER ADD YEAST TO YOUR BAIT RECIPE' !!
I would go to a grocery store and find entire tables of near rotting bananas, where I would ask the produce manager to sell me all of his rotting bananas for $2-5.00. Usually the answer is yes. Similar sources at fruit farms, orchards, tree farms. A friend once found several 55-gallon drums of liquified bananas which came off of a maritime ship coming into a US port after an at sea accident. Here at my home bananas were attractive to a colorful cerambycid species found in my bait traps that was only found in my banana-bait fruit traps.
Apples, peaches, nectarines, pluots, any varieties and bananas (singularly or in combination) are best choices for bait formula preparation. One needs to cut fruit, each into 4 pieces, then place about 2-4 cups of fruit into powerful blender, add 2 cups non-chlorinated water (potable water, eg well water is ok), and 2 cups granulated sugar. Blend for 15 seconds, then pour using funnel into water-washed empty 1-gallon plastic milk jugs. Fill only 50-60% and leave lid loose as fermentation begins immediately and for several days thereafter.
Ok Jellybean, you asked. Most everyone reading this bait trap and recipes will think 'all of this is not necessary'. Maybe so, but my bait traps have lasted at least 8-10 years and some with regular maintenance and repair into 20-30 years operating 24 hours 365-366 days continuously out in the wilds. Consider, I ran these bait traps here at my home for about 8 years non-stop and we captured about 40,000 just butterflies (mostly nymphalids) each and every year during those 8 years. So you choose those ''this not necessary thinkers' or my instructions. Obviously if you live in an apartment, go with the other guys.
Consider, I don't do any methods other entomologist have historically done to collect any insects. In the late 1960s, I began development of my own traps and my own methods for everything entomology related. E.g. I purchased two pickup trucks using the proceeds from collecting only dung beetles just here at my home. Yes, I used typical pitfall traps for certain smaller species, but I developed my own easier method to capture larger quantities of more sought after species, without need to dig holes in the ground. These specimens were purchased by collectors throughout the world only in bulk amounts, minimum order 100 pairs of one species. Still, this type of collecting for me is man-hour intensive as for decades it would take me 2 hours daily to pick up captures and ready traps (in all of my various 120-180 annually operating insect traps here at my home). Consider also, one has to afterwords spend hours daily to pin, spread, label, identify, store them. Why, because tomorrow the traps are filed with millions more fresh captures. I typically get no days off here for freezing winter temps, or snow, etc. All of our traps operate continuously even in torrential downpours of rain, storms, hurricanes, etc.
Here is a photo of my kill everything-type bait traps and second image is lid of that trap removed showing typical daily catch. Each different micro-habitat would yield a different selection of species. These typesof traps yield unbelievable amounts of high quality specimens, and of species not captured in quantities otherwise. My goal all along has been the development of traps that don't require my presence to do the collecting. I developed my kill-type bait traps because in the live-capture traps, specimens beat themselves to pieces every day. see jpg -a waste of catocala in live capture trap.

Can you recommend a recipe for a simple fruit bait for general moth collecting use by people who don't have the time and sources to develop their own?
Thanks, Jellybean

From 2011 to 2019 he was an assistant curator of entomology at the Canadian National Collection of Insects, Arachnids and Nematodes. Since 2019 he is a wildlife research and management consultant for the private sector in Ottawa, Canada. He has authored or co-authored more than 50 scientific papers and several books in the fields of insect taxonomy, cultural entomology, and molecular phylogenetics of butterflies and moths.

Our fermenting fruit bait traps operated only for about 1,270,000 trap-hours here in Louisiana. But, we never operated bait traps more than about 7-8 ft above ground level, mostly our bait traps operated at a height of near 6 feet above ground. There was a reason for this, all of our bait traps typically used around a minimum of 3 liquid gallon of bait. In my 2022 publication concerning our lifelong entomological research and collecting activities, I discussed the details of our bait trapping. We used European and Asian pears and apples, peaches, nectarines and other fruit trees, and bananas plants, blueberries, paw paws, fig trees and others, in order to obtain thousands of pounds of fruit used in operating our fermenting fruit bait traps year-round 52 weeks yearly for decades. We also used fruit from on-site wild native plants and trees at the AESS (hawthorns, crabapples, blackberries, blueberries, grapes, elderberries, currants, etc.). Typically our fermenting bait consisted of store-bought apples, bananas, figs, peaches, pears and others blended with white granulated cane sugar and regular beer and onsite potable well water. Over the past half century, we used about three+ gallons of liquid bait in each trap and topped off the containers with fresh bait every day or two during all 12 months of every year. We used over 2,000 pounds of granulated cane sugar and brown sugar, 50+ gallons of molasses and cane syrups, more than 1,200 gallons of standard 5% alcohol beer, many hundreds of gallons of wines and ethanol, numerous thousands of gallons of non-chlorinated, naturally occurring on site potable well-water, and others.
As you can see our unique trapping methods resulted in a typical trap including bait, resulting in a weight of 25-30 lbs a weight for each trap easily. It is very problematic to operate traps at greater heights as they had to be attended daily to remove captures and to constantly re-freshen the bait. At a higher height we would have to establish a heavy duty pully system to handle the large traps and the heavy baits used. There was only so much we could handle, so we did not attempt to operate them at a higher elevation. We were able to capture hundreds of butterflies daily and hundreds of underwings daily, hundreds of hawkmoths on a good day and innumerable other insects in these traps. I designed both live capture and cyanide dispatching stationary versions of our bait traps. And I published how to fabricate these as well.
Here is my 1992 3-page publication how to fabricate our live capture bait traps. Have to go, need to run traps before sundown.

That's definitely it;: Those zig-zag markings are surely singular.
We have lots of conifers of different types.
Those guides say that they seek indoor shelter to overwinter, and my 2nd photo (on blue) shows it crawling around the outside of our summerhouse (glorified shed). Temperatures are just beginning to drop a little here (from low to mid 20s down below 20C).
