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.
