When creating higher resolution textures the bees do not have stingers.

I am a texture packist and while creating textures for bees for the upcoming 1.15 update, the stingers on the bees disappear if I make the bee texture a higher resolution.  I made the bee texture at x256 and the stinger at x64, however it does not matter what resolution the stinger graphic is at, it does not show up at all.  I tried just using the original stinger graphic from the Minecraft snapshot also, but that does not show up either.
