scorpion

I'm a little stuck... Click here to teach me more about this clue!

'arachnid' is the definition.
(I know that scorpion is a type of arachnid)

'ruined crop in heavenly place' is the wordplay.
'ruined' indicates anagramming the letters.
'in' indicates putting letters inside.
'heavenly place' becomes 'sion' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'crop' with letters rearranged gives 'corp'.
'corp' placed into 'sion' is 'SCORPION'.

Can you help me to learn more?

(Other definitions for scorpion that I've seen before include "Poisonous thing" , "Poisonous creature" , "As above (Latin)" , "Stinging creature" , "Venomous stinger" .)
