This summer I'm running a BL trap for a friend who's (always!) looking for cerambycids. So far I've not seen any but have caught (and released) quite a few of these. I have never knowingly seen these before.

niche packing in burying beetles
Hi MJ,

N. sayi is a spring breeding burying beetle, so it should show up in the fall again when the new brood emerges. There's a nice paper on how the various coexisting species divide up the breeding season:

WILSON, D. S., Knollenberg, W. G., & Fudge, J. (1984). Species packing and temperature dependent competition among burying beetles (Silphidae, Nicrophorus). Ecological Entomology, 9(2), 205-216.
