Whats the Giant rattlers poison effect? Also would you like to add the tarantula hawk?
[spoiler]
The Spider/other prey animal/insect is alive, but paralyzed when the larva hatch inside and eat their way out.
I can think of no more evil creature well suited for harassing the late game survivor than these guys girls. They are the reason the normally gentle tarantulas have a tendency to rear back on their back four legs and attack things that make them uncomfortable…trying to protect that back from giant stingers…
And if they aren’t scary enough for you yet, they carry the paralyzed spider (usually heavier than the halk IIRC) back to their den where they drag them underground and inject the larve.[/spoiler]

However, the sting—particularly that of P. grossa—is among the most painful of any insect, though the intense pain only lasts about three minutes.[5] One researcher described the pain as “…immediate, excruciating pain that simply shuts down one’s ability to do anything, except, perhaps, scream. Mental discipline simply does not work in these situations.”[3] In terms of scale, the wasp’s sting is rated near the top of the Schmidt sting pain index, second only to that of the bullet ant
