Yes P. prossi. And???  Did you try and reset the elytra together? Anybody have a good technique? I relax the specimen, partially dry it then apply a clear glue underneath to fuse them, then I secure them together with pins. Does not always work tough. |

Interesting technique. The trick would be to find a rubber band that exerts enough pressure to keep the elytra together, but not enough to crush a drying specimen. Also to get it past the legs; seems like a two-person job.
Some specimens are really stubborn about that. I'll remember to try this technique one day.

intresti,g technic ! where do you put the glue and how many ? Well, obviously the glue (I often use clear nail varnish ) goes underneath the specimen, right where the elytra meet the abdominal segments. I like using nail varnish as it is quite runny and permeates the specimen, is easily removed with acetone and finally it dries clear. I have tried the rubber band method with mixed results and for a really big prionid I used plastic cable ties, unfortunately not only did the ties leave a mark on the elytra my good work came undone a few weeks later, so I'm back at square one... |

Too bad about those broken lucanus davidis, lol I did the same thing recently, they are very difficult to set without breaking the mandibles, they need to be relaxed so that the tissues start to decompose but not too much, just enough to open the mandibles |

Greetings,
This looks like a good idea to keep the elytra together, but I see a potential problem in removing the bands. It would be simple to snip them with a scissors, but a snapping rubber band would have the force to break off legs or other parts. For lucanids or big scarabs this might work, but I would hesitate to use it on more fragile groups like Cerambycidae. The explanation may be in the text, but I am unable to read it.
Cheers!
Bandrow

As for the elytra. He said can use nylon rope to tie up. Strength can not be too big. Otherwise the shard will deformation. But the effect is very good Glue general I use white emulsion. Strong glue will corrosion insect body |

Bandrow As to Cerambycidae. Shard cannot close is often shard itself deformation. It is difficult to save. But can use change pesticides method to change the consequences |

Recommend you kill beetle using ethyl acetate. This kind of pesticides is very good. Just paper suction on a bit can put the insect smoked die. And bugs will die very easily. There won't be any deformation.
If you are worried about the on the road will stink. Ethyl acetate kill worm overnight a night can bubble alcohol. Will not deformation

That's better, not quite there though.
Re: ethyl acetate, yes. It's a good solution. However, try telling that to a dealer who would then have to tell his catchers, who are probably living in a remote area and kill specimens with what they have at hand including petrol, alcohol, whatever...
