Now you're showing the rest of the hog how arrogant you are. Since when is this forum restricted to those with the expertise you have acquired over your 40--50 years of photography. Many are less competent than me but many, like you are more so. That doesn't give you the right to judge. Have an opinion yes, but not judge. I have great fun & have come up with many pic's that are quite good, not NAT GEO quality but I'm quite proud of.
Now I've noticed you joined in November last & you've rubbed some folks up wrong with your bullying attitude.
You've posted a handful of pic's which are comensurate with the expense you went to to get them & in that short time put your self up there as an expert critique. That's not what floats my boat. If you want to bully your way through your criticisms on this global forum that's fine but you're showing the world what you are, an Arrogant Bully.

A less permanent method of sedation for small invertebrates is cooling. Put the specimen, (in this case the spider) in a jar and put it in the refrigerator until it stops moving.
Take it out of the refrigerator and place it in suitable surroundings in a suitable pose. and photograph. If the pose does not look natural, wait until it starts to warm up and assumes a more 'alive' posture.

This works because spiders and other small invertebrates are poikilothermic, (cold blooded) and their rate of metabolism is slowed considerably at low temperatures.
