Thanks go out to Bev Wigney and Jeff Ogden for confirming the powderpost =
beetles of the genus Lyctus. Very interesting. I hope they do not =
spread easily.

I see that all three species are termed =E2=80=9Cadventive=E2=80=9D =
species in Majka=E2=80=99s paper. For some reason I have not come =
across this term before, and I see that it is used differently than the =
term =E2=80=98invasive species=E2=80=99, though both terms refer to =
introduced species that are running amuck in our ecosystems (our =
domesticated ecosystem in this case).
=20
Wikipedia- the definition of choice I think -
The later and more limited concept is that: An adventive species is one =
that has arrived in a specific geographic area from a different region; =
however, its population is not self-sustaining. Population numbers are =
only increased through re-introduction. After some time, an adventive =
species may become =
<https://en.wikipedia.org/wiki/Naturalization_(biology)> naturalized OR =
some populations do not sustain themselves reproductively, but exist =
because of continued influx from elsewhere. Such a non-sustaining =
population, or the individuals within it, are said to be adventives
=20
Great work by our Chris Majka, I should add. I sometimes worry about =
who=E2=80=99s keeping track of all this important species information. =
He=E2=80=99s our beetle guy!

Many thanks!

A bit more info. I see that there are 3 species of Lyctinae in Nova =
Scotia. See pages 5, 19 & 20.

Anyone have any ideas? Photos taken as best I could. I suspect her =
home will require some sort of treatment. =20
