Question on cleaning specimens for pinning

Recommended Posts

Since 2 of my female D tityus have passed away, I wanted to try to use them as practice for pinning or maybe resin encapsulation. Neither are particularly great specimens, with missing tarsi from constant burrowing during egg laying, but they're my first rhinos, so there is some sentimental value.

 

Both died on their backs (I had leaves in their containers to help against this, but guess you can't win 'em all), and had the very dark elytra D tityus get when in high humidity. I let them dry out in my garage for a couple of weeks, and the color has come back a bit, but their elytra are still very dull and dark. I'm hoping it's just residual sub left on their elytra.

 

What is the best method for cleaning specimens for pinning? Or is there any decent safe way to bring out their color? I'd rather not damage them.

Not only moisture makes it dark. Grease/oil is usually the main cause after the beetle dies.

 

 

From weak to strong:

 

dish soap/alcohol, acetone, hexane.

 

****use chemicals carefully****

 

before cleaning the dead specimen, use warm water to soften the beetle first, then open the elytra before washing for best results. if you are using just dish soap, you can rub the inside and outside of the elytra a little.

I've seen several relaxing chambers on here that mention sponges/paper towels and warm water, with a couple days time to relax; is there a simpler or better method to be used?

people use paper towels for relaxing butterflies.

 

I just toss them in warm water , fill the whole container with water and close the lid so the whole beetle is under water. repeat if the specimen joints are still hard every 30 mins.

 

you have my ig, if you want me to take pictures lol

I made a youtube video on making relaxing chambers a while ago. It's pretty straightforward, so you probably won't really have to watch it lol.

Ok, so now that I have a third dead D tityus, Im trying to look into this again.

 

Is it normal for elytra to turn almost black during drying? My two females died on their backs, so I thought the exposure to moisture was what made them dark, but theyve gotten even darker now that theyve dried for a long time. My male, however, died right-side-up, and was nice and yellow when I found him, but I can see his color getting darker over the past couple of days as he dries.

 

Im mainly wondering if Im missing something Im supposed to be doing to prevent this from happening.

Ive had this happen too, I think you just pin them and wait, and eventually theyll turn a grayish yellow with the spots.

Did they turn black after you pinned them? I have no experience with D tityus but with D granti if you pin it through the elytra, they will often turn black because the oils from their fat deposits come out when you pin it. If that happens with D granti, you have to degrease them with acetone. There are many discussions on the insect forum about degreasing.

If you did not pin it and turned more black after drying out, I don't know what that is. I have not seen that in D granti.
