to catch [ the infinitive is used to modify the word (length = a noun), so it is used as an adjective, of course,it is a verb too but it is used as an adj. in this sentence. At the same time (catch is a transitive verb, so an insect is the object of catch)]

but [40 times...] is a phrase used to modify the verb [jump], so it is used as an adverb here, so it is an adverbial phrase

i think "40 times" MAY be the adverbial phrase.
