Genus Neogalerucella (Purple Loosestrife Beetles)
Explanation of Names
Neogalerucella Chûjô 1962
Numbers
4 spp. (incl. 2 introduced) in our area(1), 9 total
Identification
The native species (N. quebecensis [QC, MI], N. stefanssoni [NT]) have elytra all pale, and are hard to distinguish from N. pusilla(2)
Range
holarctic; transboreal in NA (NS-MI-AK)(1)
Food
hosts: native spp. on Potentilla and Rubus (Rosaceae), introduced spp. on Lythrum (Lythraceae)(1)
Remarks
N. calmariensis and N. pusilla were introduced in the US from Europe and Asia in 1992 to control purple loosestrife. N. calmariensis emerges about a week before N. pusilla, first eating the leaves, shoots, and buds; then the N. pusilla eats the new growth, weakening the loosestrife, and after a few years the plants die off.
