Are these invertebrates kept and bred in zoological institutions?

[StellarChaser]

I know they may be owned by privates, but I am curious about are there any zoological institutions interested in having these species.

• Elegant Grasshopper (Zonocerus elegans)
• Rainbow Milkweed Locust (Phymateus saxosus)
• Peacock Spider (Maratus volans)
• Picasso Bug (Sphaerocoris annulus)
• Rainbow Shield Bug (Calidea dregii)
• Cotton Harlequin Bug (Tectocoris diophthalmus)
• Madagascar Sunset Moth (Chrysiridia rhipheus)
• Helena Morpho (Morpho Rhetenor Helena)
• Pyrops candelaria
• Eupholus schoenherri
• Frog-legged Leaf Beetle（Sagra buquet）
• Malaysia Fire Snail(Platymma tweediei)

I have worked in a behavioral ecology lab that bred several Maratus species. It's actually quiet easy and the six species we had were all bred the same way. But they are absolutely tiny! I wouldn't know of any benefit a zoo would have if the display them...
