Tosena is a genus of cicadas that can be found in the Indo-Malaya ecozone, which includes the Indian subcontinent, Southeastern Asia and southern China. Tosena cicadas have colorful wings, which rival the beauty of butterfly wings. Tosena are easily obtainable online from stores that sell insects, or ebay. The Tosena genus was first identified by Charles Jean-Baptiste Amyot & Jean Guillaume Audinet-Serville in 1843.
From A Monograph of Oriental Cicadidae by W. L. Distant:
Tosena is one of the most conspicuous genera of the Cicadidae, and its species are all included in this fauna. The north-eastern districts of Continental India are its head-quarters, for here are focused some of the largest and handsomest of its species ; it is also well represented in Burma, and from thence its distribution is extended throughout the Malay Peninsula to the south, and apparently northward as far as some portions of China. In the Malayan Archipelago it is not uncommon in Sumatra, Java, and Borneo, and as I have seen representatives from Amboyna, it probably exists in other intervening islands, of which, however, we have at present no precise information.

I have a collection of se Asian insects in a sealed shadow box a wanted input on ceasing them in clear resin worried that they may break down if left in the shadow box. Please advise
I keep mine pinned in cedar boxes, with a little naphthalene (moth balls) to keep the dermestid beetles from consuming them.
I think it would be possible to preserve them in resin but you might have to experiment with different types of resin to get it right. Cicada bodies are mostly hollow, so after you pour the resin, air bubbles will release and the abdomen may collapse. Maybe fill the abdomen first. Maybe a vacuum chamber would help removing the air. You might have to experiment to find a resin that doesn’t change their colors.
