Chun, I often find these spiders running free, hidden under a leaf (http://www.projectnoah.org/spottings/157...). They are at least double the size of the Argyrodes I found in webs. My guess is that these bigger ones are perfectly capable of stalking and hunting large preys.

Only Sergio can tell whether this is a kleptoparasite.
Does it has its own web or is it living in a larger web owned by another spider?

Nice one, Sérgio! Congrats.

Thank you, Daniele, for giving me this honor again. No matter how many times it happened, it is always like the first time. And thanks also for mentioning my spiders album, most people are so afraid of them that they do not realize how beautiful they are.

Great find Xara,very cool ,congrats on the well deserved SOTD and thanks forsharing

Congratulations Sergio, your Dewdrop spider is our Spotting of the Day:

"This Dewdrop Spider (Argyrodes sp.) is about to have a large tasty meal in our Spotting of the Day, but was it responsible for catching it? Spiders in the genus Argyrodes (family Theridiidae) are kleptoparasites: they take preys that have been caught by other spiders.
Find our more about dewdrops spiders and kleptoparasitism in this blog piece written by Project Noah ranger, insect guide book author and writer Eric Eaton: https://buff.ly/2EdYGCN
