The female Megarhyssa wasp, a genus of ichneumon, has been observed tapping a tree with her antennae to pick up vibrations of a larva living an inch [2 cm] or more beneath the tree bark.
Emast Megarhyssa - käguvamplast on nähtud tundlatega puud koputamas, mis aitab tal tajuda rohkem kui 2 sentimeetri sügavusel puukoore all vastse tekitatud vibratsioone.
