Per Frank Howarth at the Bishop Museum: “I cannot be sure from the photo, but the pattern and general form match the recently introduced cobweb spider, Theridion melanostictum Cambridge, 1876 (Family Theridiidae). This species is occasionally abundant on foliage in urban and agricultural areas, and the males (which this is) are wanderers and therefore noticed.”

Stripe-leg Garden Spider

Dorsal view close-up.  Body length is 2 mm.

A toad sitting on grass.

Per Frank Howarth of the Bishop Museum: “This one is most likely Zosis geniculatus (Olivier, 1789), family Uloboridae. Zosis spiders make an orb web, but it is often at an angle or horisontal rather than vertical like the true orb weavers. They also use at least some hackled threads to catch prey. The orb weavers use glue.”
