If you google the name from that spider field pic, an interesting article about the critters can be read.
This caught my attention:
Wasps are another problem for tarantulas. Several varieties paralyse tarantulas with their sting and then lay eggs in the spider’s abdomen. When the eggs hatch, the paralysed spider is eaten alive by wasp larvae. Even the goliath birdeater is not immune. The particular species of wasp that feeds on the goliath is the size of a sparrow.
Wasp. As big as a *expletive deleted*ing sparrow. Holy *expletive deleted*it.
