Other common names: Brazilian White Knee Birdeater, Brazilian Black and White Striped Birdeater, Brazilian White Banded Tarantula, Giant White Knee Tarantula
Scientific name: Acanthoscurria geniculata
The Brazilian White Knee Tarantula is a large, beautiful terrestrial tarantula species which is native to Brazil. Acanthoscurria geniculata are commonly found under rocks, tree limbs and logs, and in captivity need to be provided with lots of hiding places. As they are a burrowing species, their habitat also needs to include a substrate they can create tunnels in.
Like other ground dwelling tarantulas, the Brazilian White Knee Tarantula can be defensive, and it will kick urticating hairs when provoked.
Appearance / health:
As their common name suggests they are black and white. They are banded at all leg joints and between these bands, white stripes run vertically. These tarantulas are large and can reach size up to 9 inches.
Behavior / temperament:
Brazilian White Knees are a defensive and aggressive species. They will not hesitate to flick hairs at any perceived threat. If flicking the hairs off its abdomen doesn’t work, and it still feels threatened, it will not hesitate to begin biting. Because of their aggressive temperament, it’s not recommended for beginners. These make great display pets for more advanced and expert keepers.
A large cage is needed to house an adult. A 15-20 gallon tank will be suitable. Floor space is more important than height. Young tarantulas and spiderlings may live in clear plastic containers until large enough to be placed in the adult enclosure.
Temperature range for this tarantula should be 80-85F with humidity levels of 75-80%. Substrate should be a mix of sand, vermiculite, potting soil, or clay and should be damp enough to hold shape but not drip water. This will allow this tarantula to burrow, although it’s not likely. A shallow water dish may also be provided and cleaned frequently. Add tank décor that will help this tarantula hide or burrow under. It’s not good at climbing so be careful not to put any sharp or pointed décor that the tarantula may fall on. Cork bark, driftwood, plant pots, and others may be added.
Since the Brazilian White Knee Tarantula is a fast growing species, it’s a very voracious feeder. Crickets, cockroaches, super worms, grasshoppers, and other large insects may be fed. Larger adult specimens can get an occasional pinkie mouse for more variety. Spiderlings and younger tarantulas can feed on pin head crickets and fruit flies.
gorgeous spider, show piece, stunning, Great display animal, great eaters, incredible eaters
handling, semi aggressive nature, experienced tarantula enthusiast, difficult husbandry requirements
subtropical species, reputable breeder, humidity issue
Stunning looking species, easy to keep
Let me first preface my review by saying that all tarantulas are individuals, there is no telling what they may do.
With that said, let me say that Marta (female) is one of my favorite tarantulas, and also one of my most gentle. I have handled her many times with no issues whatsoever. These are normally NOT considered handleable spiders by most people. Apparently, Marta missed the memo, haha!
Pros: There are many.... These grow to a good size (8" or so). Their appetite is almost legendary, the only time mine refuses food, is when she is pre-molt. These are most often visible, I provide Marta (as I do with all my T's) with a bark hide... She has used it maybe twice, ha.. Most often she sits on top of it, scanning for prey. As stated before, My girl is very calm. Handling, photoshoots, and re-housing her are simplicity itself.
I do want to mention one thing: I feel some people mistake this species' brutal feeding response for aggression. In all honesty, I think they are big bluffers. Once, tired, I just stuck my bare hand in her tank (not recommended) and she instantly whirled around, latched onto my thumb with all her forelegs... then a half-second later... noticed I wasn't food, and she just stormed off!
Again, tho, your mileage may vary.
As for cons to the species... well, there aren't too many, in my opinion. As they get older, they can become hair flickers. Marta is a bit of a flicker. Beyond that, they may not be very easy to obtain, one's best bet is a specialised tarantula / invert dealer.
That's about it, fantastic spiders.

Big, attractive species
This is a large, confident, strikingly attractive spider - as the name suggests, they have bright white streaks on the knees. This is a chunky, ground dwelling spider that is usually quite happy to be out and about and visible, although will appreciate a hide to create a safe burrow. Big appetites and sometimes big personalities to boot. I've found them a little hit and miss as to whether they are docile or aggressive.
The simple test I do with spiders is to tap the spider on the abdomen with something like a pair of tongs - just lightly, this won't hurt it. If it swivels around, rears or tries to bite then it's aggressive, if it runs forward very fast then it's flighty - but most adults of this species I've encountered will either ignore you, or simply meander forward slowly. Then you know your likely to be dealing with a calmer spider!.
