Looks like a bagworm to me. Many people associate them with junipers and other conifers, but they will set up housekeeping in any kind of plant, using its leaves to make its cocoon. BUT! I could be wrong....that's just what it appears to be.

i go with norfolk ... not sure its really a pine ... so go with the latin name ... its a houseplant for most of us.. and i recommend that forum if you are going to keep it potted ... i am not sure its a full sun plant in a pot .... and that is why it does ok indoors .... i am sure it can do great things in its native habitat.. but that would not include a pot ... you dont mention where you are.. it might not favor winter outdoors ... they are extremely cheap at bigboxstore... i dont recommend spending a lot of money to try to save this rather common plant ... it most likely needs to be repotted.. and so i include PROPER MEDIA in the cost .. ken

Towards the end of the summer once my corn is all gone these same type of critters will start attacking my tomatoes for a backup food source.

All winter while the branches were exposed my husband did not really like this tree because of the gnarly and almost distorted looking branches, ==>> you tell this dude.. that peeps bay doubel or triple.. for the gnarly plants ... and that you are going to take away his man tools if he ever sets foot near any of your prime plants again ... and dont let him get away with claiming such ignorance.. just to get out of doing some work for you in the garden .... now.. whether this plant have any life left inn it... thats a different issue ... im thinking it might be time to get rid of it.. the basal shoots indicate the top of the tree is in bad shape.. and that is supported by the water shoots also trying to take over the plant ... it is too big a tree.. planted too close to the house.. so with all that going on.. id probably vote for removal ... though it would be a good tree to learn how to prune on ... remove it now. or in 3 years.. whatever.. tree time is counted in decades;.. so no hurrry regardless ... ken
