They start by sniffing along dead wood to identify the presence of food and use their long, middle digit to tap on wood in search of subsurface cavities (Erickson et al., 1997). 

Use their large and elaborate ear structures to detect a change in frequency along the wood to detect cavities that may contain invertebrates (Ramsier & Dominy, 2012). 

They then use their incisors to gnaw a hole into the wood. Finally, they insert their elongated third digit into the cavity to extract the larvae (Masurkar et al., 2023).
