ok i would like to get one thing straight here. dubia are capable of flying. thats that. ill tell you what has been happening. so when i maintain my dubias cages, i leave the top open because im always exchanging foods andegg crates and what not. and this is why they are escaping. its sorta a myth that males have wings but dont fly. thats weong. males have wings but dont fly when they dont have to. i have discovered this for my self. ive heard roaches at night and when i find them, they are ALWAYS males. 5 times now and i only have 15 or so males. its getting really annoying cuz my family hates roaches and i get in trouble whenever they find one.(still yet to come ) especially this time. about 10 minutes ago i was going to the bathroom ready to go to sleep when my sister yells saying one of my animals escaped and is in her room. "Oh ****!" is what im thinking. im dead. so i look for a while dont find anything and claim its a mouse in the wall or something.(it was making squeakin sounds) she insists o look more and she leaves while i look so i open her closet and a male dubia flies across the room into a junk pile in her room. i find it and say it was a cricket cuz of the squeaking chirpy sound. im really fed up because they seem to always escape and im just tryna tell people who think roaches are easy to keep in their cages should think about it. keep a cover on the cage. always close the cage too. roach escapes are not usually welcome with your girlfriend or maybe boyfriend, many times family or spouses.
