Is this a pest and is it affecting my washingtonia robusta?

I’ve repotted my washingtonia robusta several times and it is growing fine. Some of the older leaves look affected by something other than age.

I am wondering if I am having an infestation of some kind of pest. I find these guys on the leaves just kind of hanging out. Low energy little guys, they let you just pluck them right off. The size is hard to tell but they are roughly under 1cm in length. They look like a weevil almost but they’re small. They may also be in the crown of my palm causing problems.

what is this bug and how do I get rid of them if they are causing my tree problems? Thanks.

Looks like a weevil, but hard to say w/ out a face shot.. Regardless, majority of weevils will have snouts. 

If your palms have outside through the summer, this kid might just be passing through and caught while just hanging out on the palm before moving on..  If you're finding more, that could be an issue ..though i can't think of any Weevil sp(s) -that would live where you're located- that might bother palms ..Not to say that one being native there isn't impossible..

Aside from manual removal when you see them, might put up one of those yellow sticky traps to try and lure /  catch any others that might be around, if any besides the one caught,  are..

Only time i'd consider something more serious ( Soil drench to kill any in the soil ..or palm itself, etc.. ) would be if you notice dozens of them in /around the soil/  palm(s) themselves.

Hope this helps..

Thank you for your response. I think I may have identified this as a “vine weevil” .. first time I’ve ever seen one. I’ve been manually removing them but there’s a small population of them I must’ve gotten from the soil I chose to repot the tree in

Looks right.. Did not realize these were as widespread here in the states, let alone here in the western U.S. ..regardless,

would employ a sticky trap or " tanglefoot " -type barrier around the trunk(s) ..if big enough to install something like that.  Certain Nematodes can be applied to the soil to kill grubs as a natural control option as well.
