In one my adventures of having pet spiders, I was doing yard work out in the front yard and came across a small insect that interested me, so I put the little bug in one of my spider bottles and kind of forgot about the tiny thing. I came across the bottle a few days later and learned that the spider in the bottle had died but that the tiny bug i had put in a while ago was not so tiny. in fact it was the only thing alive in the bottle and had been feeding and eating on the dead and decaying spider food. I transferred the bug into the main bottle I had which had two or three cellar spiders and the little bug lived in the bottom of the bottle. I named the bug Teddy and watched as he grew and molted bigger and bigger.
It turned out that Teddy was an assassin bug. Assassin bugs are actually pretty cool bugs. They have a very long mouth piece that is referred to as a beak which they use to quickly attack their prey and eat them. When they bite their prey, they inject a strong poisonous toxin that liquefies the preys tissue so that the assassin bug can eat it. Assassin bugs are good for the environment and for farmers, because they control some unwanted pest species that can be a hindrance to humans. They will eat just about anything if they are hungry.
Assassin bugs have six legs and two antennae. They have a hard exoskeleton that can protect them from enemies. When they become adults, the assassin bugs have wings underneath their exoskeleton that they can use to fly. I only saw Teddy jump around and try to fly. He couldn't go very far seeing that he was inside a habitat.
Teddy brought a good balance to the habitat I have because he would take any uneaten food from the spiders and eat it himself. He was a good addition to the spider habitat. Unfortunately, he was taken and eaten by a spider in the habitat after getting too close to the spiders and falling into the web. This was all about a year ago. I haven't come across anymore bugs like him, but if I do, I'll be sure to add it to the habitat. :)
