Other common names: Yellow Mealworm, Yellow Mealworm Beetle
Scientific name: Tenebrio molitor
The Mealworm Beetle is a species of Darkling beetle (Tenebrionidae) which was originally native to Europe, but which is now common worldwide. The larval stage of the Mealworm Beetle is called the Mealworm, or Yellow Mealworm, and it is both a pest for stored grain products, and a popular, and nutrient-rich food for the global pet industry.
The female Mealworm Beetle lays up to 500 eggs, and 10-12 days after hatching, the egg hatches and produces larvae. Yellow Mealworm larvae can grow up to about 30 mms in length, and are popular food for captive reptiles, small mammals, fish and birds.
While mealworms they are most commonly bought in cartons, some animal owners raise their own mealworms. Raising mealworms saves money, and is considered quite easy when using a substrate of different grains.

"These are an excellent treat for my birds and are a great meal for most anything that eats worms. They are so easy to keep but as a complete opposite of the fruit-fly - these guys eat rotting meat too!! YUCK!!<br><br>I tend to keep them in a meat composter with a hole that lets them escape or rather fall out for the birds which gives them a welcomed treat from time to time and gives me a use for my discarded meat goods from the trap line or butchering chores.<br><br>Some days, the younger birds head straight for the meat barrel in anticipation of what creepy crawly they may find, even before their first drink of water some days!<br><br>Mealworms are a great source of nutrients for many animals and aside from their terrible smelly homes serve an extremely important purpose on the farm and in nature of course.<br><br>-photo is a stock photo from the Wiki Commons -."

"I keep these little guys for feeders for my tarantulas and my Chameleon. They are slower movers than superworms and also smaller, so they are great for smaller species of Tarantulas and ones that like to wait for their privacy from you before making their move to eat. One thing I don't like about them is that they seem to die faster than superworms, so you have to purchase them more often if you are using them a lot. I personally have never tried breeding them, and haven't found much information on trying to do so, so if you are looking for a feeder that you don't have to go purchase every time, this isn't the feeder for you. ."

"I first started raising these for my chickens, since I bought them I figure why not raise them instead. They cannot drink water like you would normally water things. They drink water form watery foods like potatoes, carrots, etc. You have to slice them up and put them on the top of the bedding and change them when they dry out, which in the summer here is everyother day. Their bedding is cheap, you can get this stuff called grain mill, which is the leftover from milling oats, barley, etc from a feed store and it is cheap cheap. They do not reproduce quickly and the larvae will eat the eggs of the beetle, so you have to sift the bedding often to remove the larvae often or you wont have any reproduction. The worst part is that their poop is not good for you, after working with it for a while and as the poop starts to build up you can and probably will become allergic to it, and I have been told it can be serious. When I learned this I fed them all to my chickens that day, cause I cannot afford to get hazmat clothes, silly sounding but true.."
