what a great shot! Thanks autiger85  couldn't believe they keep colour as nature,but they are! ;D i also take great interets for the preserved larva specimen and would like to learn some and make myself! the instruction was nice detailed. yet not enough. it would be better that put the photos processes. any other links available for the introduce of presevered larva specimen with photos of process available? there're several different abit methods for making preserved Caterpillars/larvas that i ever searched some to read. but seems autiger85's methods is the best directly seeing from the photos. and good for long time preservation. |

came across this old thread a few days ago and was happy to see someone found a way to easily preserve larvae. However using this silicone method this week Ive been unable to get decent results. Ive tried it on some Manduca sexta and Paonias myops larvae. Within a few hours the larvae develop brown spots all over them. Does anyone know what im missing or possibly doing wrong? I sent the original poster a message a bit ago, but it seems they have not been logged in for a few years...
Anyone else here tried it with acceptable results Id be glad to hear about it
Thanks
Greg

I too will try this as soon as I get some larvae and report back... |

I too will try this as soon as I get some larvae and report back... The method of filling with Silcona was the discovery of Dr. Andrés E. Varga (Argentina) in the year 1995!!! and this discovery was published in its book "Argentinean Butterflies" Volume 1 in the year 2000!!!!! Even the Dr. Bernard DABRERA he fascinates this method (for the stranger) in opportunity of being in the year 1995.... The reading of the book is attached (in Spanish) and some caterpillars that possess but of 15 years of antiquity (Morpho catenarius argentinus). If they fall to the floor "they don't break"..... PARDON FOR MY BAD ENGLISH..... www.mariposasdelmundo.com |

:)The product used in Argentina is denominated "Fastix" (I attach it photographs) that is a siliconas cream to seal glasses, metals, wood, etc.etc. And the utility to be used for filler of caterpillars was discovered when newly you invention the product ". For it, I cannot believe that no person finds overdraft this use before her Creation!!!!!!! Please, I don't simply want no person to be thought author of this discovery since the same one was made and published many years behind.... Attachments:

Interesting technique but it looks like the silicone (and squeezing out the guts) greatly distorts the shape and size of the body. For displays this looks great, but for retaining scientific value I'd recommend boiling the caterpillar and storing in ethanol. The color doesn't isn't preserved but the shape of the segments and placement of the setae is most important.

I know this is a very old thread now, but just wanted to chime in as I attempted the method with my cats. In almost all cases, they either turned black or developed areas of blackness that basically ruined them. I believe the key rests in "fixing" their colors ahead of time first, before any silicone filling is done. This is done by either one of two methods I've read about online: 1) Drop recently acquired cat in boiling water for 1-3 minutes. I tried this. Colors do change a bit/ some fading & darkening, but not turning spotty or black later. 2) Fixing with acid and Xylenes as described here: insectnet.proboards.com/post/2974/thread. I have not tried this method, only #1. There actually is another method I'm in the process of trying, hoping to preserve both color and the cat. A fairly rapid freeze drying method: images.peabody.yale.edu/lepsoc/jls/1970s/1976/1976-30(4)277-Hedges.pdfAs luck would have it, a friend of mine had the actual aspirator the author used, but I don't think which one matters although I might be tempted to steer away from the plastic ones. Hope this helps anyone who is still having troubles! |

Just to follow up on my earlier post, I tried this method and have had much success, in fact the ONLY method I found to both preserve and dry Monarch caterpillar. Colors are almost completely intact. I let it go a little bit longer than the 2 weeks recommended (18 days), but couldn't be more happy with the results. |
