Randy & Dave et al : this past June while at MV lites with Saturniids. Ni.
pustulatus was more common at the sheet than the ordinarlily common june bug
Phyllophaga sp or Polyphylla sp and just as noisy and annoying ! Just my
observations . My suspicion probably only uncommon because probably not
that many people out at nite around lites looking for these critters.
Cheers , DB

Dear All, Aug 26, 2008
Today while hauling firewood, I found a large attractive Carrion Beetle
(Necrophila americana (L)) in a pile of Populus grandidentata that was cut,
split and piled in 2007. It was quite at ease with having been exposed,
sitting with antennae splayed foreward and not moving at all and remained
equally calm when I moved it to a post top. More than 5 minutes later it
moved away and presumably flew.
Most predators require movement of their prey to initiate an attach (hence
your mother telling you never to run from a threatening dog). That carrion
beetle was not very likely "at ease with having been exposed", rather it was
likely "scared poopless" (I figure that term will get past the filters!) for
fear of being detected. Of course both descriptions assign emotion to an
insect that likely has none.
I have previously seen this species only once, on freshly split dead
Populus tremuloides (Sept 24, 2004) about 150 paces SE.
This is a relatively common carrion beetle, somewhat more so in open
habitats, but found in the forests as well. An image can be found at

And on Aug 17, 2008 I found Nicrophorus pustulatus Herschel (another large
Barrion Beetle) in a nearby pile of White Ash firewood that was cut live Jan
2008.
Now this one is uncommonly caught, though I'm not so sure it's because of
rarity. My student's work this summer found it four times more often in
hemlock dominated woods compared with deciduous woods. Most who catch it do
so at lights. By the way, there's an interesting slip-of-the-keyboard
above..."Barrion Beetle". Although Ni. pustulatus is a Carrion Beetle, more
specifically, it is a Burying Beetle.
Like gold and everything else, Carrion Beetles are where you find them but I
wonder if they are there as hunters or for shelter.
Ne. americana is diurnal, Ni. pustulatus is nocturnal, so where you found
the latter is more likely to be its shelter.
