Subject: Long Fine Webs + Egg clusters on trees. Los Angeles.

Hello,
I live in the Whittier area of Los Angeles. I’ve noticed long fine webs and occasional egg clusters on my deciduous trees branches, and a young bougainvillea. The bougainvillea was eaten down to the stems, not sure if related.
Webs span between branches, and are usually single strand. The webs can become come somewhat more complex in crook of branches or near buds. The small white eggs can be singles, but I have seen long clusters of 1 dozen or so. I never notice any insects present.
My trees are young, between 1-4 years old. Not sure if I should be concerned, or if I should treat. Don’t want to let it get out of hand if its dangerous to my trees. FYI – trees are various fruits, and several Mexican Redbud.
Any insight would be helpful. Thanks.

Hi Erin,
Webs are generally associated with spiders, but your web and eggs are not related to spiders.  Many caterpillars spin silk, but caterpillars do not lay eggs, so we don’t think this is related to a Moth.  We will post your images and continue to research your submission.
