Spider drama in fourteen parts of life and death

This little spider drama in 14 parts played out in my shed on the side of an old white bucket.
“Continue reading” for this dramatic sequence soon to be a major film. 14 photos.

The players include:
Spider A appearing first above. A juvenile female redback only a few mm long belongs to a family of spiderlings presumably from the same brood that live on the side of the bucket. (The males are about 1/4 the size)
Spider B is a slightly bigger lighter colored female from the same brood.
The bug – alive but only intermittently making movements during the drama.

Above. Spider A has caught a huge bug (about 2cm) in her tiny web. The bug is only intermittently moving now and is being wrapped up. A lot off excited running back an forth.
The bug is being lifted up.
Enter Spider B, probably big sister but still tiny compared to my finger tip.
Coming down to investigate the commotion.
Above, both spiders appear to cooperate in wrapping up the monster meal.
Suddenly, without warning Spider B turns on Spider A and starts to wrap her up.
The hapless Spider A seems surprisingly passive.
I watch somewhat horrified as one sibling continues to wrap up the other….
… and then takes the bug, painstakingly up to the rim of the bucket and her lair.
Above, back at the lair, evidence of past dastardly deeds, or so I thought. Is there no honour among spiders? Actually, this is probably a moult.
The bug is now stowed away.
But, hey, Spider A hasn’t completely stopped struggling. After an hour she gets one leg free. After 2 hours she is free but still removing the wrapping thread.
By the next morning she is well and seems unharmed. I was secretly hoping this would happen. So a happy ending in a battle of big against small, good vs evil. Unless you were the bug that is.
