spider webs spreading

Posted by kellycat florida (My Page) on

Hello, I've seen several different kinds of spiders in these webs. From a med/small with sort of a flat brown back to small & very very small spiders. It has me worried because they are spreading throughout my yard/plants/trees.
Does anyone know what these are and why are they invading my trees.
Help!

I doubt those are Spider Webs but they most likely would be the webs that one of several moth larva would make.

unless you are a witch.. and can hover up there on your broom.. to see whats up there ....

i suggest you call your COUNTY extension office.. and ask them what current plague is in your county ...

notice that the branches beyond the web.. are barer than that below... that suggests caterpillars ... rather than spiders.. which arent insects ...

Kellycat, please describe the problem in more detail. Are these webs on a variety of plants? Are these just in your neighborhood? Have you been able to see the culprits, close-up?

The image you've presented appears to be of the webbing from Eastern Tent Caterpillars, but your added description of spiders confuses the issue. Can you clarify?

Webbing from tent caterpillars.

Disrupt the webs (if you can reach them) so that the birds, etc, can get to them.

You can look here for your county's Cooperative Extension office:

I have seen them in my neighborhood too on the central west coast of Florida. Must be a caterpillar year.

I've seen 3 different kinds or shapes and sizes of spiders in these webs. Some very small black spiders, very small green spiders & small to med size brown spiders with a flat back. I did see some caterpillars one day, but I mostly see the spiders. Thank you all for your help! And thank you to the person who posted the site for the county ext svc. I'll give them a call.

Really, these webs are not created by spiders. If spiders are present, they are there by chance. Spiders are beneficial and eat a lot of pest insects. They do not eat the leaves. These are made by tent caterpillars which do eat the leaves.

+1

Birds love to eat the worms if they can get through the web. Though, when we had really bad infestations in NE, we would cut them down and burn them.
