Sigara limitata (Fieber 1848)

This is a widespread bug that prefers gravel or pits and ponds in Northants with vegetation. It is only recorded in smaller numbers and needs some detailed identification to correctly distinguish it from other small Sigara that are usually found in the same communities.

Adults overwinter and there maybe two annual broods.

Size: 6mm to 6.5mm
Emergence period:
GB IUCN Status: Least Concern
Northants status: Scarce
Number of records: 15
Number of sites: 11
1km squares recorded: 11
5km squares recorded: 11
10km squares recorded: 11

Distribution:

This is widely distributed across Northants and scarce, found in just 11 sites . The Nene valley is an attraction with the many Clay and gravel extraction sites. They are not abundant in those sites but are regularly recorded there in small numbers.

Habitat:

JD, 2007 identified his habitat in Surrey as relatively open water over silt in pools, canals and drains, often in new ponds associated with aggregate extraction and that is similar to Northants although we also find an association with clay ponds with some vegetation such as Stoke Bruerne Brick pits and sandy Lane drainage lake.

Identification:

These are a trick group to identify but are a little smaller around 6mm to 6.5mm and fit into the smaller Sigara group below 6.8mm. From here it is a mix of features that includes 7-9 lines on the pronotum, a matt surface with 2/3 dark lines on the corium, a very deep facial depression that goes as high as the top line of the eyes, dark swimming hairs on the hind leg and a distinctive set of of pegs on the male palae.
