Whatsthatbug.com ?

I came across this website just the other day and the following day I walk out onto the patio and came across a cool looking bug I've never seen before... Here's what I sent in to whatsthatbug.com, and they even posted my submission on their website!  :)

"I just came across your website the other day and low and behold I head out to garden this afternoon and see this little guy in my backyard!  I've lived in West Broward (South Florida) all my life and never seen one like this... It was lying on my pool deck and seems to be on his (or hers) last limbs :(  I placed the little guy on a plant after I took these pics. It has two pairs of wings (which is reminiscent of a wasp, but it also has a proboscis, and very, very long antennae and legs. What is this South Florida creature? Is it even from here?

Sunny South Florida

South Florida, West Broward County"

Turns out it's a Milkweed Assassin Bug! OMG!
