Sawflies

Athalia rosae Turnip Sawfly   7-8 mm. This species has an orange thorax, abdomen and legs contrasted with black head and 'shoulders pads' and a black front edge to its wings. The adults feed on nectar visiting a range of flowers, often cruciferous plants and umbellifers. Larvae can be pests. No records for GMC concentrated in south.

 

Arge cyanocroce, Bramble sawfly  A distinctive fly with a black head and thorax and an orange body. The wings have a distinctive wide dark band across. The legs are reddish. Seen around hedgerows and foraging on umbellifers such as Hogweed, where the adults take nectar and pollen. Common in the south but reported in GMC at one site in Trafford.

 

Arge berberidis berberis sawfly First British record was in Essex in 2002, since when it has been recorded in most southern counties, and NBN has it in Yorkshire and South GMC. To be found on berberis and mahonia plants

 

Eriocampa ovata (Alder Sawfly)  The adult sawfly has a black head and abdomen and dark orange thorax

It flies around Alder. The larvae camouflage themselves as bird droppings. No records for GMC mainly South UK.

Hoplocampa sp  There are a 9 species in this genus, measuring 3-7mm. They are either all black or all pale yellow found on friut trees or hawthorn. Fairly widespread throughout Britain

 

Tenthredo mesomelas sawfly, 4-5/06/11 This sawfly has an apple green body with a black back. It is set apart from the similar Rhogogaster species by its black stigma. It is  seen around meadows, verges and woodland rides, where it takes pollen and nectar from umbellifers as well as small insects. Thought to be common but inly in south GMC.

 

Tenthredo notha sawfly A large lemon-yellow and black sawfly. Very similar to T. arcuata and T. brevicornis and  difficult to separate so tentative. Adult takes small insects and visits umbellifers for pollen and nectar

 

Tenthredo livida Sawfly This sawfly has white mouth and white tips to its antennae and variable in colour, sometimes all black, but other forms with red. The white marked antennae together with the white and brown stigma in the forewing are distinctive and help with the identification. Found along hedgerows and woodland rides

 

Tenthredo livida Sawfly This sawfly has white mouth and white tips to its antennae and variable in colour, sometimes all black, but other forms with red. The white marked antennae together with the white and brown stigma in the forewing are distinctive and help with the identification. Found along hedgerows and woodland rides

 

 

Rhogogaster viridis This common sawfly is one of several similar R. chlorosom . The pterostigma (the coloured mark on the front edge of the wing) is uniformly green or yellow in this species and it has a small black line on side of its thorax. Best character is the relative length of the pads on the back of the tarsal segments . A thin black line in the groove on the side of the thorax is often a good clue for viridis. Few records GMC.
