Lesser Bees and Butter Bees are especially the same snake....butter/lesser have been "dubbed" different lines of the same morph. They are both double gene animals with the butter bee "butter spider" being a combination of butter and spider, and the same with the lesser bee being that of the lesser and spider genes.
Spider to spider breeding have proved to show a high mortality rate for some reason, including those of combo spiders....it still has the spider gene so it will still do the same thing, most of them die in the egg or don't make it past a couple of days out of it...
There is much debate whether the spider gene is really a co dominant mutation or dominant and since none of these so called "super" spiders have lived to prove that they can produce sole spider clutches they are marked as dominant...however someone produced what they believe is a super spider that is still kicking after a couple months, so hopefully that can be the key.
Spiders also tend to have what people refer to as "wobble" when they get excited....usually when stressed or on feeding day. Some are more noticeable than others, but they usually all have it...it's just about how noticeable it is.
Hope this isn't to confusing and helps.
