Greenbottle Blue Tarantula (Chromatopelma cyaneopubescens)

Greenbottle Blue Tarantula (Chromatopelma cyaneopubescens)

The Greenbottle Blue Tarantula is one of the most colorful arachnids out there. These spiders are native to the dry regions of Venezuela. It is the only species in its genus, Chromatopelma. Females can live around 15 years, while males live only about 3 years. This species can grow quite large, growing up to 6 inches in legspan, and they grow at a medium to fast rate.

They are highly sought after by tarantula keepers because of their stunning blue, green, and red colors, they like to stay out in the open, and because they make large, elaborate webs. This terrestrial/semi arboreal tarantula is usually docile, and their venom is weak. They are a very good beginner species, although they can be skittish. It is best to keep them on drier substrate with a lot of anchor points for their large webs. They don’t burrow much, preferring to create tunnels of webbing instead.

The Greenbottle Blue is one of my favorite species because of the webs they make and their beautiful coloring. I got mine, an immature female, from Fear Not Tarantulas. They are the best place anywhere to get a tarantula or various different invertebrates. If you are looking to get a tarantula, go to or visit their store in Virginia Beach, VA. Like I said, the Greenbottle Blue is a great beginner species for anyone looking to get their first or second 8 legged friend.

Tarantula Terminology

Tarantula Terminology

Greenbottle Blue Tarantula, GBB (Chromatopelma cyaneopubescens)

There are a lot of terms in the tarantula hobby, and it might seem a bit overwhelming for a beginner. Here is a list of some common tarantula terms and their meanings to help you understand more of what experienced keepers have to say.


DKS: Dyskinetic Syndrome, a series of symptoms of unknown causes, including jerky, involuntary movements, and an inability to eat. This usually ends in the death of the tarantula, as there is nothing you can do to save it.


GBB: Greenbottle Blue Tarantula (Chromatopelma cyaneopubescens)


LP: Brazilian Salmon Pink Birdeater Tarantula (Lasiodora parahybana)


MF/AF: Mature/Adult Female


MM/AM: Mature/Adult Male


NW-New World: Native to the Americas


OBT: Orange Baboon Tarantula (Pterinochilus murinus)


OW-Old World: Native to anywhere else

Hot: Highly venomous.


Invert: Invertebrate, any animal lacking a backbone.


Molt: The shedding of an arthropod’s exoskeleton so that a new, larger one can take its place. Molting is the most vulnerable time in a tarantula’s life.


Molt Mat: A layer of silk that tarantulas put down to protect themselves during molting.


Premolt: The period of time when a tarantula stops eating and becomes sluggish in preparation for a molt. A tarantula may be in premolt from a few days to months.

Brown Recluse Look-Alikes

Brown Recluse Look-Alikes

One of the most infamous spiders in the U.S. is the Brown Recluse Spider (Loxosceles reclusa). Also known as the Violin Spider for the patterns on the cephalothorax, these arachnids possess strong venom, and bites are very painful. The venom sometimes even causes the skin around the bite to rot.

There are many spiders that look similar to the Brown Recluse, causing harmless spiders to be confused with the recluse. One such spider is the Brown Spitting Spider (Scytodes fusca). These small, harmless, slow moving spiders are brown in color and share the same natural range as the recluse, but they can be identified by their trademark large, dome-shaped cephalothorax.

Another similar spider is the Wolf Spider (Lycosidae sp.). There are many species of Wolf Spider, most being a brownish color. They are very fast and some can get quite large. Their bites are mildly painful, about that of a bee sting, but they are not aggressive and are usually docile. The best way to identify a Wolf Spider is to look for the large front facing pair of eyes.

 There are many, many brown colored spiders out there, but it isn’t possible for me to name all of them here. Those listed are just a couple of the most commonly mistaken for Brown Recluses. Remember: Just because its a brown spider doesn’t mean that its a Brown Recluse! If you find a spider that you would like identified, just send a few good pictures of it to me at and I will get back to you as soon as I can!

Wolf Spiders: Caring Mothers

Wolf Spiders: Caring Mothers

Did you know that Wolf Spiders are excellent mothers? When a female Wolf Spider is ready to lay eggs, she weaves a sheet of silk to lay them on. Then, she lays a hundred or more tiny little eggs on the silk mat. After the eggs are laid, the spider then weaves a sac of silk around them. She attaches this egg sac to her abdomen and carries it around for a couple of weeks until the eggs hatch.

 When the eggs begin to hatch inside the egg sac, the mother rips a small hole in the sac to allow the spiderlings, or baby spiders, to climb up onto the mother’s back, where they will stay for the next few weeks. Once they are fully developed and ready to fend for themselves, the spiderlings will climb off the mother’s back and skitter away into the undergrowth, fully capable of catching food and defending themselves.
