Hi, I am emailing from Houston, TX. Recently my neighbor discovered hundreds of caterpillar like insect larvae on his pine tree. They are about 1/2 inch in length, yellow-ish with black dots on their back. There seem to be a few leg-like structures near the head. I did my google search and am leaning towards 'pine sawfly larvae' as the closest match. The tree is deteriorating. It's losing its needles, and some branches are completely free of needles. He treated the tree with a spray insecticide yesterday (sorry, don't know which one). My questions, is it likely to observe pine sawfly larvae in November in Southern Texas? I am afraid I miss-identified the problem. Is there anything else we can do, in particular to prevent the spreading of the insect from one tree to the next (which, in this case, would be mine....). Thanks, Tim.
