Having done the same thing when I was starting out.

I've been trying to pin them out correctly, I suppose inexperience will change over time. Out of curiosity, what have I done wrong with this one? Thanks.

For the former it is esthetically pleasing to symmetrically splay legs and antennae of pin-mounted specimens which should ideally be displayed under glass of a dermestid-proof insect box. These specimens should not be crowded and there should be no or minimal handling to avoid appendage breakage. However, I prefer a "scientific" collection in which I handle pinned specimens regularly for study under a stereo-microscope. For such a collection, all my beetles have legs loosely tucked beneath body and antennae pulled back along side head/pronotum. The appendages are "set" to these positions while the specimen is still flexible when freshly mounted. Also, I prefer a much smaller data label (laser printer type) than the one shown here. Top label is locality information (at least State, County, Date), bottom one is identification.

you need to move the appendages closer to the body. Spread out like you've got it looks good but it takes up a lot of room and is a sure way to have the appendages broken off. Check out this
to see what I'm talking about. Scroll down to "Specimen Preparation."

I can't control my artistic side, so I pin most of my specimens like Erik:-) I've had relatively few problems with breakage, but will agree things take up a lot of room that way. Further, doesn't a tightly arranged specimen obscure characters you need to see? I'm hoping to one day get many of my specimens imaged, too, and I think I will be glad I put some effort into the aesthetic aspect. To each his own?
