The Caddisflies (Trichoptera) of Nottinghamshire
In our efforts to highlight the county's less studied invertebrate Orders, it seems that we continually write about the lack of current knowledge and interest in those Orders. Trichoptera (Caddisflies) are no exception, especially in terms of the general lack of interest showed in them by today's naturalists.
There's a similar lack of interest showed in Neuroptera (Lacewings) and to be honest, much of this is brought about by the assumption that Caddisflies are difficult to identify, cannot really be done from photographs and that the use of a scalpel and microscope is essential.
Whilst a microscope is required for some species, a number of Caddisflies can be identified from good quality photographs and there's obviously plenty of species to identify in Nottinghamshire.

Perhaps rather surprisingly, it turns out that there are some 6,300 Caddisfly records, representing a total of 108 species found in Nottinghamshire.

Caddisflies in Nottinghamshire

Nottinghamshire's 108 species, comes out of 200 species presently known from the UK. Just over a century ago, J.W. Carr in his book 'The Invertebrate Fauna of Nottinghamshire, published by J.& H. Bell Ltd in 1916' mentions some 65 species in Nottinghamshire, out of a total of 174 species recorded in the UK at the time. Carr goes on to mention that 'many more will doubtless be found when the Order is more systematically worked' and he states that he 'was grateful to K.J. Morton for determining most of the county's species/records'.

Because so little information on Nottinghamshire Caddisflies was available on the internet, we thought it time to publish something which could spark some interest. They are a much neglected order and we are not aware of individual in the county, who is presently recording them.

Thankfully, we were contacted by Ian Wallace in early 2019. Ian runs the UK Caddis Recording Scheme and very kindly supplied us with the current Nottinghamshire species list below. The majority of the Scheme's Nottinghamshire records have come from the Environment Agency and the dataset of Bob Merritt. Bob privately sent us his invertebrate records a number of years ago, after he stopped his invertebrate recording in Nottinghamshire and moved up to Scotland.

The National Trichoptera recording scheme

The Nottinghamshire species list produced above, was compiled and made available to us for publication by Ian Wallace. Ian runs the UK Caddis Recording Scheme, which has 6,300 records for Nottinghamshire representing a current total of 108 species known from VC56. The majority of records come from the Environment Agency and are of common flowing water species. The Scheme's iRECORD data has been made available to the Nottingham Biological and Geological Records Centre (NBGRC) at Wollaton Hall.

Ian regards Nottinghamshire as an under-recorded county, suggesting that the lack of Caddisfly records conincides with the lack of identification keys to live adults. A new guide is in preparation and will hopefully be available in 2020, but photos can be sent via the iRECORD system and will be verified by Ian where possible.

For adult Caddisflies, the standard work to dead specimens is the Royal Entomological Society Key of 2012 by Peter Barnard and Emma Ross.  It was always a little daunting for those just getting in to Caddisflies, so the Freshwater Biological Association has just published an introduction to the group written by Stuart Crofts. (For larvae there are the two keys available from the Freshwater Biological Association that require dead larvae and a Simple Guide, from the Field Studies Council that enables identification of those that can be done when alive.)

There are many phtographs of adults now available on the Web but Ian would draw attention to the image bank accumulating on iRECORD and also the NatureSpot website. Ian can be contacted directly at
