Just came across your site, and it’s fantastic! Can you confirm whether this little darling is a Micrathena sagittata? Most of the sagittata photos I have seen show this species with much more yellow than black. This photo was taken at Cumberland Island, GA, in August.
Hi there Karen,
You certainly do have the Arrow Shaped Micrathena here. This is a shot of the underside, hence the markings look different. Additionally, there is often much variation from specimen to specimen.
