Just remeasured mine by hand. The adult is indeed about 1cm, or 3/8", nowhere near 3/4". The nymphs are a little smaller.

They were found in a loading dock area on three separate traps, in opposite corners of the room, April 1 - July 1. The loading dock is part of a newly refurbished building and has some leaky spots to the outside that we haven't been able to address yet. I've been monitoring the space since the fall, and this is the first I've seen of them.
