ナガシンクイムシ科あるいはキクイムシ科(要同定)




ナガシンクイムシ科(bostrichidae)なのかキクイムシ科(scolytidae)なのか、、

  • 2月12日(水)。ecp。
  • Coast Live Oak (Quercus agrifolia)の大木の葉の表面でじっとしていた。
  • 何を食べるのか分からず同種の木の葉を一度取り替えて、2週間経過した2月26日現在も生きている。
  • 同定については、dc氏が次回のLorquin会合でナガシンクイムシ科に詳しい専門家に相談してくれるそうなので、当面はこれに期待。

要和訳:dc氏より転送:This midge induces round-tubular monothalamous galls that hang from the bottom of arroyo willow (Salix lasiolepis) leaves.  The distinguishing character of these midge galls is the apical hole or depression that develops at the end of each gall.  While most of the gall hangs below the leaf, there is usually a slight depression on the dorsal surface.  Galls are commonly pink to rose red with hints of yellow and green.  Galls may develop singly or in coalescing groups of four to five individuals. These midge galls measure 5 mm high by 4 mm wide at their base.  Gall development begins in spring in the central coast area of California.  This species may occur outside of California and throughout the range of the arroyo Willow group.  While the biology of this species is relatively unknown, larvae appear to leave the gall by autumn.  Presumably,they pupate in spring.  Willows that retain their leaves into fall and winter may continue to support the galls of this species.
