The date for Moth Night in 2020 has been set for 27 - 29 August.  The theme for Moth Night 2020 is to be the various "Red" Underwings - Red Underwing Catocala nupta; Rosy Underwing C. electa; Dark Crimson Underwing C. sponsa and Light Crimson Underwing C.promissa. As in previous years, you don't have to target the theme moths if you feel unable to.  One of the main themes of the event is to go out, record moths and enjoy yourself.  As always we welcome public events as part of the MothNight.

Public events are an excellent way to share the fascination of moths; if you are organising an event you can have it featured on this site by entering the details here.  

Moth Night is normally held in the warmest months; each event will last for three consecutive nights (Thursday – Saturday) and will take place on different date periods every year. You can participate on any one or more of these days or nights. 

Organised by Atropos, Butterfly Conservation and the Centre for Ecology & Hydrology, Moth Night is the annual celebration of moth recording throughout Britain and Ireland by moth recording enthusiasts with local public events aimed at raising awareness of moths among the general public.

Atropos originally founded Moth Night in 1998.  Atropos is the UK journal for butterfly, moth and dragonfly enthusiasts. It is published three times a year, with an annual Migration Review. This website is a resource for visitors to find out about latest sightings, how to get involved in recording in their local area and to share information with other enthusiasts. If you would like to subscribe to the journal you can do so by clicking here.  AtroposBooks offer a wide range of books on butterflies, moths, dragonflies and other invertebrates.

Butterfly Conservation are the UK's leading charity devoted to the conservation of butterflies and moths, and their habitats.  They run the National Moth Recording Scheme.

The Centre for Ecology & Hydrology is a world-class research organisation focusing on land and freshwater ecosystems and their interaction with the atmosphere.  They manage a range of long-term environmental monitoring sites and networks across the UK.

Participants are not required to comply with the theme and are encouraged to do their own thing.

In association with the Biological Records Centre at the Centre for Ecology & Hydrology, we have designed an easy-to-use Indicia-based online recording system available from the first day of the event until the deadline for data entry.
