Giant praying mantis.
I mean, it's a good description. It preys on things, and its big, and its a mantis.
Just pray it isn't a high level if you see one and you aren't ready...
The leap is as big as the U.S. President's net worth...

If you want to find a Dino that is cool but a pain to tame, the mantis is for you

Give it a whip to hold it has a great visual bug (accidental pun also thus may be fixed)

Don’t you love it when your on the beach and you think look it is a big mantis let’s hug it and it leaps at your face
