Thanksgiving dinner conversation....

As we gear up for Turkey Day next week, I thought I would pop a bit of knowledge into the back of your brain that you can share with dinner companions. 

As you sit at the dinner table with your group, you can casually say "Did you know that there are allowable amounts of insects in our food?"

"No!" your companions will gasp.

"Yes!" you will insist.  "I learned about it on this really great blog I read.  You should subscribe to it!"

So, if you don't believe me about bugs in your food, check out this FDA site that has all the information you need for your conversation (and probably a bit more.....).

HAPPY THANKSGIVING!

Green lynx spider

Today our Travis County Master Gardener volunteers were working in our demonstration garden to tidy things up.  I always love when they come out as I get to interact with them directly with hands-on teaching moments.  Today, I was not disappointed.  One of them came in to see if I could tell them about a spider she found.  You can look at the title to figure out what it was....

The spiders that we found were mommas with babies...in this case, spiderlings.  You can see in the photos webbing that encases part of the plant also holds and protects offspring.  The female spider guards her spiderlings until they can fend for themselves. 

Lynx spider with spiderlingsSpiderlings remain near the egg sac for a little over a week and then they disperse to new locations by ballooning.  Ballooning is where spiderlings throw up a strand of silk to catch the wind which carries them to a new location.  I hope that I am here when this happens as I found four lynx mommas with babies (that could be about 800 spiderlings!!).

Asp a.k.a. puss caterpillars

These have been a hot news item lately in Central Texas.  I did a news interview & Facebook Live broadcast yesterday to talk about them.
Asp or puss caterpillar
While these teardrop shaped caterpillars look soft and touchable, they are NOT! Asps have spines attached to venom glands that can lead to a nasty sting, rash, and other issues. Some people may have a more severe reaction than others and where you are stung (thickness of the skin) can effect things. You can read my previous post on asps HERE.

My technical skills are lacking, so I have no idea how to share the Facebook Live video outside of Facebook, but if you want to see it you can go to KVUE's Facebook page to find it.
