Weird bug on clementine tree
hey all. I'm new to growing fruit/veggie plants and I got this clementine tree from Pam fast growing plants. It came and some leaves had holes in it but otherwise it looked good. When I planted it I noticed more tiny holes popping up and I clipped them. I've been spraying it with diluted detergent to prevent more bugs. But today I found this rather large guy and I was curious if anyone knew whether or not it was harmful?
I also have a mind plant plant near by and it's had some thing flying out/eating it's leaves as well. There are also white meshy loking spots. Dunno if that's from spider?
thanks for the help!
