June 3, 2020

Location: Maritime Hammock Sanctuary, Melbourne Beach

These are the egg sacs of a Brown Widow spider
Each one contains over a hundred eggs
The sacs are white when first constructed
When the eggs inside hatch, the sacs look dark grey*.

Brown Widow spiders are venomous
They belong to the Theridiidae family
They are also known as comb-footed spiders
Because of the comb-like bristles on their hind feet.

Note: The sacs don't actually turn dark grey, what looks dark grey are the baby spiders inside the sac.
