I think those are called "junebugs".
Jujubes (pronounced "ju ju bees") are shaped like their eggs, and named after them, although technically not a "bee". Or "ju" for that matter.
No one has ever seen a Junebug. However their reputation has achieved mythical proportions, because it is mythical.
I think I've gone over the line, dateline, here.
