Wow! Gorgeous!
There are spiders everywhere
How pretty!!!
Beautiful spider!
Beautiful ?
We have lots of orb weavers here on Vancouver Island. In the spring, when the previous years egg mass begins to hatch, we begin to look forward to their flight. On a dry day with a bit of breeze the tiny, dot sized young spiders each produce a miniscule bit of silk which they release into the breeze and this silk balloon (still attached to their spinnerettes) carries them, one by one (and there are hundreds), away to their new home.
We would love some images next spring. If you send them, please use the subject line “Spiders Ballooning” and we will be sure to notice.
