Nephrotoma I thought to be appendiculata

Submitted by colinleb on

In spite of the dark stigma I thought the inverted 'U' on the pleurae meant this must be Nephrotoma appendiculata.  However it was at Hexton Chalk Pit (VC 20) on 25 June 2014, which is rather late according to Stubbs (2021) (April to early June).  Posted pics on Facebook Cranefly Group page and am advised that blunt cerci rule out appendiculata, suggest analis?  Keys to that species in Stubbs but dorsal stripe on abdomen is wide (should be narrow) and location doesn't seem right.  Overnight quadrifaria has become the Facebook favo

help id, wich Siphona

Submitted by Svavar on

hey all. i found this Siphona in my kitchen window 31/7 Denmark (DANIA.NEJ.NJ96) 

its about 5mm, and it looks like geniculata due to 4 dc after suture, and bright/light brown/yellow tegula and basicosta.

BUT ???

according to this key, it should not have longer palpi than 3rd antennal segment, but it does. could it be another species ????

Sarcophaga haemorrhoidalis

 A friend sent me this picture, taken in his garden in Salisbury, Wilts, asking for confirmation of his i/d.  I am pretty sure he's right but would welcome the views of others before putting the species on the Wiltshire list.
