Mosquito Recording Scheme

33 species of mosquito (Diptera: Culicidae) have been recorded in the British Isles, five are either rare or doubtfully native as they have not been recorded for many years. The aquatic breeding sites adopted by British mosquitoes vary considerably. The requirement of mosquito larvae and pupae to breathe air, limit them to relatively still, sheltered and shallow waters. Some species develop in permanent waterbodies such as ditches and ponds, while others occupy temporary freshwater pools in woodlands and flooded meadows or saline pools in saltmarshes. A few species are "dendrolimnic", occupying the water that collects in tree-holes, while others are found in great numbers in containers such as rainwater butts in urban areas. One British mosquito selects underground water that collects in flooded basements, the foundations of dwellings, drains and underground railway tunnels. Mosquitoes adapt to their many habitats and aquatic sites by developing differing survival strategies, particularly in coping with periods out of water and surviving over winter, and their preference for haematophagy and their role as disease vectors, makes this family of Diptera a fascinating group to study.

Following Keith Snowís work in running the British mosquito recording scheme, Jolyon Medlock in collaboration with Moray Anderson will now be taking on this role and have been working with the Biological Records Centre to make all current and historical data available through the NBN Gateway.

Many of our endemic species are heavily under recorded, and the potential exists for new species to be added to the list. We therefore welcome all records of Culicidae, or indeed samples for identification.

Re: Mosquito Recording Scheme

I am currently looking at mosquitoes in Ireland using light traps. Does anyone have suggestions on the best way to supplement them with co2 (Iíve been using dry ice chips in plastic container punctured to allow the gas to escape). Iíve seen no real difference between light traps with co2 or those without, has anyone had more success using different methods? Any suggestions would be very much appreciated!

Re: Mosquito Recording Scheme

It's a dim and distant memory but I recall that when producing anaerobic conditions in my microbiology days we used a GasPak system in which tablets of a mixture of citric acid and some bicarbonate or other, released a mixture of hydrogen and carbon dioxide when water was added.
A bit of basic chemistry might lead you to a solution smile
Let's hope they are not simultaneously repelled by hydrogen sad

Excellent news o the Recording Scheme. Is there a site about Culicid flies anywhere, to aid IDs and to read up on where best to look for less-typical species at different life-stages?

P.S. Cranston, C.D. Ramsdale, K.R. Snow & G.B. White: SP 48. Mosquitoes (Culicidae)
Keys to the Adults, Male Hypopygia, Fourth-Instar Larvae and Pupae of the British Mosquitoes 1987, 152pp. ISBN 0 900386

£13.00 from FBA http://www.fba.org.uk/index/books/scipubs

Its has very good keys of adults, it relies on very small features of what are smallish flies anyway. so if identifying pinned specimens a good scope with good lighting is needed. I suspect slide mounting may be preferable? I have only collected a few specimens this year as I didn't really look out for them. But given the fun I have had identifying these few, I will possibly look out for more this coming year.

My, very limited experience, Like Tipuloidea, legs often fall off, but unlike Tipuloidea, legs are needed for identifying many of the UK species.

Re: Mosquito Recording Scheme

Ah... that's interesting - the legs are pretty much the important bit. I take it then that a dead specimen would be pretty easy to identify? I have steromicroscope with WD20x eyepieces. Suitable?

Re: Mosquito Recording Scheme

I would say X60 minimum, (for me thats X20 eyepiece, X30 Objective) and even then one struggles to see tarsal claws etc, I can go higher, but then light is the problem.

A lot of the FBA stocks of publications have been destroyed in the November floods, so it may be worth getting the above book sooner rather than later?
