Spider and tarantula hunting wasps always amaze me. I like the colors of that particular species, I haven't seen it before. Sucks for the T though, I hate to see them being predated
In insects and arachnids the stages are very distinct. Sexually mature, or not mature. No gradation in between. They either have reproductive organs and structures, or they do not. In mammals there is gradation. Mammalian primary and secondary sexual structures develop gradually, not in a single molt.But let me ask, aren't their degrees of maturity? If it isn't fully mature yet, but somewhat mature, then don't you think it could be gravid?
There was someone on another board who rescued a tarantula that had received the paralyzing sting from a wasp, but had not yet been buried with the egg deposited on it. The tarantula survived, but was "numbed" for quite some time. Finally, though, the wasp venom wore off and the tarantula recovered. A truly rare event, but at least in this one case it worked.No, that spider is done for.
Yeah, makes sense too. I see these wasps sting each individual spider multiple times depending on how much the spider fights back. So you can guess that the venom isn't a real killer, the cocktail doesn't shutdown or destroy vital areas instead only 'numbs' or 'disables' their mechanisms. How inefficient would the reprodutive journeys of these wasps be if their venom resulted in leaving the larvae to hatch out to an already dead/rotting/rotted/molding spider to eat?There was someone on another board who rescued a tarantula that had received the paralyzing sting from a wasp, but had not yet been buried with the egg deposited on it.

Not size, but anatomical structure.Well if that was the case, then shouldn't there be a known size for every species of tarantula at which they should be able to reproduce at?
I don't follow.Not size, but anatomical structure.
Ok, here the situation.I don't follow.
Exactly. Some animals simply grow larger or smaller than the average for their species. Being big does not mean they've reached maturity, being small doesn't mean they haven't.Not size, but anatomical structure.
