We’ve seen this spider in our front yard in the same place for about three months. It seems to have a yellow outline of an hourglass on its belly. We’d like to know what kind of spider it is and if it’s poisonous.

Dear Matthew,
This beautiful Silver Garden Orbweaver,
Argiope argentata, is considered harmless, though large individuals might bite if carelessly handled.  Most spiders are venomous, though very few have a venom powerful enough to threaten humans.

Thanks very much!  I’m glad it’s considered harmless.  We will leave it alone then.
