yes, depending on the sizes.
ANSWER
No...it cannot eat it, its poison would most certainly be enough to kill the tarantula but a black widow would be eaten the instant the tarantula senses it.
it is the kkk and black widow
there both spiders
A tarantula will be the best out of the three of them because their venom is the least potent and the tarantula is the least aggressive depending on the species,the chaco golden knee and the pinktoe tarantulas are known to be calm.But if you have to choose between a black widow or a brown recluse a black widow is better because there not fast runners,but never keep a black widow or a brown recluse because there has been recorded deaths from them but no recorded deaths on tarantula bites,so even if the tarantula is more expensive its the one that wont be able to kill you,although make sure your not allergic of bee stings or a tarantula bite can be fatal
black widow eat sun scorpions which eat locuts and grasshoppers. black mamba eats black widow vultures and hawks eat the black mamba
The Sydney funnel web spider
is it a tarantula? if so, it's a Mexican redknee tarantula. http://www.Google.com/search?hl=en&q=Mexican+red+knee+tarantula&btnG=Google+Search
black widow, brown recluse, and many others, but those 2 are the most common in the u.s.
there are many huge spiders. tarantula, daddy long legs, black widow etc.
The Black Widow or the Tarantula Edit: Sorry to change your answer, (I'm a different person) but you are half-wrong. The black widow is the fourth deadliest, while the Brazilian Wandering Spider, a distinct species of tarantula, is the most venomous.
Yes, a tarantula Hawk could certainly kill a black widow spider if it wanted to. A black widow spider would be too small for a tarantula hawk to bother with most of the time. Actually, black widows are a favorite meal for some types of mud wasps. The wasp will sting the spider - paralyzing it - not killing it. Then take the black widow and stuff it inside the nest it's making for it's off spring. When the wasp larvae are growing, they'll feed on the paralyzed spider. This is the same basic thing that a tarantual hawk does with the much larger tarantula spider. While you can find video's of black widows appearing to catch and kill wasps, this is definitely the exception rather than the rule. A wasp can run into trouble if it finds itself tangled in the spider's web, though most of the time they're able to navigate their way around it and deliver the paralizing sting before carrying the spider off to it's nest.
True spiders i.e. Black-Widow or Tarantula belong to the Order Aranea in the Arthropoda Phylum.
the blackwillow does no eat the her spiderlings
