Bee nests should use wax blocks, not skeps as their texture. It is a common misconception that bee 'nests', or wild bee hives as it were, are shaped like a spiral or Michelin man. These in fact are representative of skeps, a traditional form of manufactured bee hive before wooden framed hives were popularised.
Natural beehives are generally found in crevices like holes in trees. Naturally, this is not practical in Minecraft. However, beehives are sometimes found hanging from branches, a la the implemented design. These hives are, of course, made from beeswax. The beeswax texture proposed would be perfect for bee 'nests'.
I would even suggest that the manufactured hives be replaced with skeps (and renamed a Skep), using the present texture for a bee nest, albeit with only one hole. Skeps would be made from either sugar cane or wheat, make in a dome-like fashion on a crafting table. Skeps would have to be placed on a block and cannot be suspended. Everything else would remain the same. Otherwise, the present wooden beehive could remain and the skep texture removed.
I feel Mojang has a responsibility to promote accurate knowledge, and given the proliferation of misconception regarding the appearance of beehives, they have a duty to be accurate.
