Red Admiral Invasion Year in Great Lake States?

[Jonathan Sylvestre]

Here in center Québec (Manseau) I observed a great number of V. atalanta
since a week ore more. They are nearly everywhere and they are flying in a
SW-NE direction most of the time. If I remember correctly the lasts times
they invaded Quebec in great quantity, I can tell that they are more
numerous than ever !

I did not see any other Vanessa species yet, but i did no field trip since a
week.. its pretty cold here and we had some snow yesterday. The V.atalanta
seem to handle that well.

I was wondering if other people in the Great Lake States region are noticing
a much larger than normal influx of Red Admirals (Vanessa atalanta) this
year. Since April 30 when good numbers of Red Admirals ( 30 to 40 at single
sites) were first reported in both Northwest Monroe County and Southwest
Washtenaw County of Southeast Michigan, Red Admiral migrants seem to be
everywhere. So far they have not reached the highest levels of the last
Vanessa invasion year of 2001 or have been accompanied by major influxes of
sister Vanessa species American Painted Lady (V. virginensis) and Painted
Lady (V. cardui) but the season is young.
