They do look mirrored to me, at least some of them. In that case it is just half as much work  . |

I use points or cards, just glue the beetles onto the point or the card, and then try to arrange the legs, you might need to use a stereoscopic microscope. But sometimes, I just leave the legs alone, or arrange the antennae. I usually do it after I've identified it to species. Another method is to use minuten and minuten strips, for beetles that are between ten and 20 millimeters.

Actually these tiny beetles aren't too difficult to set like this.
I kill them with ethyl acetate, then leave then in the vapour for 24 hours, then glue them to cards under a low power binocular microscope.
The legs and antennae are moved into position with a couple of setting needles I made with match sticks and minutes pins.
With a little patience, really tiny ones can be set.

This subject has been discussed several times over the years. I use a "double-mount" method using .15 stainless steel minutens for small coleoptera. It takes a bit more time, patience and dexterity but the results a well worth the effort - especially when viewed under a microscope.

I normally don't use pins for tiny beetles, I glue and spread them like that (not mirrored...) |

In my opinion, the matter is how to set the legs in the right position. Often when I try to spread them, they return to their original position under the body as soon as I release the needle or the forceps... even with fresh specimens.
