Broad-Headed Bug

While scouring the bordering-bricks in the front yard, I came across a Broad-headed Bug of the species Esperanza texana (subfamily Micrelytrinae, family Alydidae). For the longest time I couldn't determine even the superfamily, much less the family or genus. I knew only that the bug belonged to the suborder Heteroptera (True Bugs), and that it was related, at least distantly, to stink bugs and plant bugs. But at last I figured it out! That's a good feeling. I'm afraid my photos are quite as crisp as I'd like (and that may be why I had so much trouble identifying the bug), but you can still see some of the main features of the bug (antennae length & shape, body shape & color, leg color, etc.).

For a comparison of Broad-Headed Bugs to stink bugs, plant bugs, and seed bugs, consult this site:
http://www.cals.ncsu.edu/course/ent425/library/compendium/heteroptera.html. Remember, Esperanza texana belongs to the family Alydidae. For helpful diagrams, scroll down to 15b on Dichotomous Keys.

You'll see an earwig retreating across the bottom right of the photo.
