Cone-feeder
Guides
Conophthorus coniperda
white pine cone beetle
Conophthorus coniperda, the white pine cone beetle, is a scolytine weevil that develops entirely within the cones of eastern white pine (Pinus strobus). Adults emerge in spring to attack new cones, and larvae feed on cone tissues and seeds, often killing the cone. The species is typically univoltine, though some individuals require two years to complete development. It is a significant economic pest in white pine seed orchards due to seed destruction.
Dioryctria pygmaeella
baldcypress coneworm moth, cypress coneworm moth
Dioryctria pygmaeella is a snout moth in the family Pyralidae, described by Émile Louis Ragonot in 1887. The species is restricted to the coastal plains of the eastern United States and eastern Texas. Larvae feed within the cones of baldcypress (Taxodium distichum) and pondcypress (Taxodium ascendens). The species completes up to three generations annually.
Dioryctria zimmermani
Zimmerman pine moth
Dioryctria zimmermani, the Zimmerman pine moth, is a conifer-feeding moth in the family Pyralidae. It is a significant pest of pine trees in the midwestern and northeastern United States and southern Canada. The species has one generation per year, with adults emerging in late August and eggs hatching through mid-September. Larvae bore into pine bark and cones, causing damage to host trees.
Lasiomma
Lasiomma is a genus of flies in the family Anthomyiidae, established by Stein in 1916. Several species are known to be significant pests of cones and seeds of European larch (Larix decidua), causing damage in the natural range of this tree in the French Alps and Italian Piedmont. The genus has been recorded from multiple European countries including France, Denmark, Norway, and Sweden.
