[obol] Townsend's Warbler food item

[Maryln & Lou Balaban]

I wondered about Crane Fly larvae also. There are many adults flying 
around here in the late summer and fall and brown spots in the lawn.

A WSU website says: "The European crane fly, Tipula paludosa, is a 
pest which has become established in the Pacific Northwest including 
British Columbia."

And a french one:
"Larva: 3 to 4 mm, apodous, earthy grey colour. The cylindrical body, 
soft but very tough extends and retracts considerably; the head can 
be retracted, lending a tightly packed, pudgy appearance.
- Larva: the young larvae feed on humus and vegetable waste matter 
which is more or less rotted. It is still small in size (1.5 mm) at 
the start of winter. Highly resistant to cold, it overwinters near 
the surface of the ground without diapause them becomes active once 
more in the spring. It digs underground galleries open to the air 
allowing it to emerge at night.
- Life Cycle -1 generation per annum for T. paludosa, the most 
harmful and widespread crane fly in Northern Europe, the larvae of 
which can cause severe damage from January to May."
