Found a few different insects on my magnolia tree this morning.
2 x spiders
1 x possibly a type of egg?
1 x small white insect (spotted about half a dozen of them all towards the end of the branches just below the new leaf growth)

Are any of these potentially bad for the tree? Most curious about the white insect and the possible egg.

THANKS!

1st two are spiders. I don't know what #1 is but #2 is a jumping spider, Phidippus sp.
#3 could be a whitefly. It's hard to tell.
The last one...I don't know.

It looks like some kind of meally bugs or other scale insect nymph, they do positioned them self near leaves vein/ribs to get more plants sap. get rid of it...

Where in the world are you located? That would help with ID's.

Hello! sorry located in Melbourne Australia!
The tree is a magnolia teddy bear, evergreen variety.
I have done a bit of searching and believe that the white insect is a mealybug (bad news) and what i originally thought was an egg is in fact an insect known as a pink wax scale (also bad news).
