entomology - Identification of fuzzy insect in Pennsylvania

I live in south eastern Pennsylvania, USA. About a month ago I came across this very peculiar insect. Its body was about an inch long, it was fuzzy, and it had a long proboscis(?) and long orange legs. I've been wondering about it ever since. Can anyone identify it?

Answer

This is the nymph of a bug (Hemiptera) from the Genus Arilus, probably Arilus cristatus, also known as "wheel bug".

Here is another image of it, for comparison:
