this thread is fucking HILARIOUS. I'm so glad I checked it out.
The original spider-cricket thing that started it all is called a Cave-cricket. And here's my story:
My brother-in-law and I were working on my house. We had to insulate my crawlspace. There was, oh, about 2 feet of space between the ground and the floor. So, basically, not much room to shift around. I covered myself up as best I could, but my neck and face were exposed (despite glasses and a breathing mask.)
Now, I am not deathly afraid of spiders or bugs. However, when I was 14 I was sitting in my room and a little spider fell onto my metallica sheet music (I was rocking out). I squashed him. The next day I was rocking out again (I just HAD to perfect my one man rendition of "One"). Another one came down.
And another.
I looked up. THEY COVERED MY CEILING. THEY WERE THERE YESTERDAY!!!! They were there whilst I slept. gwaaaahhhhhh!!!
I ran out of my room screaming like a little girl. I still get freaked out when a spider "surprises" me. But if I notice it, I usually collect the poor little guy or girl and toss him outside to devour the delicious mosquitoes. I even have a glass and a piece of junkmail dedicated to this task.
Anyway -- that's just backstory.
I climbed into the crawlspace and turned over to face the floor. I moved out of the way so my brother-in-law could get in. I turned on my flashlight. And I saw these:

Although, what I actually saw was more like this

I quickly shrieked and scurried out of the crawlspace yelling: "Space crickets!"
There were probably 100 of them living under there. All sizes. With their beady little eyes and slow moving, really long antennae. They can jump pretty far (a few leapt around my feet when I was trying to get out). If even one had jumped on my face, I would be writing this from a mental institution.
I managed to get a picture by simply jamming my camera in the crawlspace and pressing the button. From that point on, I made sure all of my skin was covered. I was convinced that the "stinger" would poison me instantly. But apparently they just inject their eggs into dirt with them. But the idea that they might inject their eggs in me is still kinda there in my mind.
On a lighter note, these things come up from my basement alot as well. My dog likes to chase them, but they can jump so far that she never catches them.
