Barbra,

I am petrified of ALL spiders. They just give me the willies! Shudder.

If they look like black widow but white... then could they have been baby black widows? Black widows look white when they are babies. Just be careful... wear gloves or something when you're near them.

If they're pale greenish then I think they're good spiders. I have lots on my plumies and I never see any damage from them. Pretty sure they just eat thrips and stuff.

They were probably crab spiders hunting for insects attracted to the blooms.
Poor little things. Laugh.

Here is a link that might be useful: crab spiders

I think they must be albino crab spiders, they are solid white. I found them only on the plumeria plants. Very pretty spiders, did not see any damage on the plants, but did not want to take any chances. I over reacted once and killed an entire swarm of ladybugs. They did not look like ladybugs, when they were all stuck to one another, swaying in the wind. I just panicked when I saw them. It was hugh, black and buzzing, I got the wasp spray and killed them. I did not know they were ladybugs until it was too late. Barbra
