Nonagria typhae - Bulrush Wainscot

 The Bulrush Wainscot is found exclusively in Typha species, most frequently Typha latifolia - Greater Reedmace. The following pictures were all taken from Typha latifolia.

The species overwinters as an egg which hatches in April/May. The larva feeds internally on the Typha stems occasionally changing plants and leaving large entrance and exit holes.

 The larvae are initially  transparent, but take on a cream colouration as they mature.

The larvae continue to grow until they reach about 4 cm. in length.

Pupation takes place in late July (note the shed larval skin to the right):

Emergence is in late August. This is a newly emerged female, about 25 mm. long.
