Frame cost me $4, background was a recycled grass beach mat, flowers another $2. Back of frame has collection data and map as well as information about the cymothoe in general. Got the A- sangaris from advertiser Ianni. Attachments:

Ooooooh, really pretty.
Just a question, but do you worry about gradual acedifying of some of the components, like the beach mat? I think it wouldn't make a difference in terms of aesthetics for color of the mat as it wouldn't change much if at all but I don't know anything about how the specimens handle it. I have been hesitant to use non-archival materials around butterflies because I don't know better one way or the other so I just avoid thus far. Do you have any insight into this winged?

Very good question to which my answer may not be adequate. The leps are glued to a styrofoam piece and so are "floating about 2 centimeters above the mat. They do not make contact with it. I am mostly concerned with preventing pests. I mash up moth balls and place them in the glue. I use a silicone glue to seal the frame to make it as air tight as I can. I have one Trognoptera brookiana which has remained unchanged in its frame since about 1977 and I keep it as my control. I THINK it works fine as long as the interior is dry AND the lep is not touching the mat. Another concern is that if I do not use enough glue, the lep can get knocked loose. A repair is them much more difficult than making a new one. I have witnessed pins in individuals in trays which have corroded as to nearly ruin the leps. For this reason, I also remove the pins after drying.

Ah ha, I see. They look like they are right on the backing in the picture, elevating them make sense. I wonder if acedification has any effect on them anyway. I've seen a fair number of specimens with non-archival labels that have turned golden brown and started to flake but the specimens looked fine. Maybe it doesn't bother them anyway. Good idea to incorporate moth balls into the adherent media, very clever.
Again, really nice display. And again, your daughter is really really cute. So precocious in that picture in the other thread, she reminds me a bit of my sister when she was that age- digging in the river mud and all.
