Insect Identification Please?

I found a small (around 1/2 inch. long) insect crawling on my window this morning. Is mottled brown with wings which are clear w/brown around the edges. Has preying mantis characteristics and "hangs" it's front legs around it's "neck" when not using them to climb over things. Has long, slightly curved under rear part (no stinger can be seen if it exists at all). Found in Texas Coastal Bend Region (near ocean).
