Mobile phone app to help monitor UK’s native ladybirds after foreign invasion

Press release issued: 10 May 2013

‘iRecord Ladybirds’ a free mobile phone app is launched today to help monitor the impact of the invasive Harlequin ladybird on the UK’s native ladybird species. The app was produced by scientists at the Centre for Ecology & Hydrology working with the Nature Locator team at the University of Bristol.

The new app will enable people to contribute more easily to the UK Ladybird Survey whose results have already shown declines in native species such as the 2-spot ladybird in response to the arrival of the harlequin ladybird, first recorded in England in 2003. 

For many insects 2012 was a challenging year and ladybirds were no exception.  Harlequin ladybirds and most native species were reported to the UK Ladybird Survey in lower numbers than previous years except for the mildew-feeding orange ladybird for which the number of records remained stable.

Tens of thousands of people have already contributed to the on-line UK Ladybird Survey and with continued help from the public using the new recording app, the Survey hopes to discover whether the UK’s native Ladybird species bounce back in 2013, as well as gaining further insights into the invasion process over the years to come.

Dr Helen Roy from the UK Ladybird Survey said: “I have been inspired by the number of people getting involved with the UK Ladybird Survey via email, online recording, twitter and traditional pen and paper – the observations they submit are invaluable.  With the new app we now have a further opportunity to continue monitoring the harlequin ladybird alongside other species to further our understanding of the invasion process.”

The app can be downloaded by searching for "iRecord Ladybirds" on the App Store app on your iPhone.   An android version will be available in the near future.

The Nature Locator team has now developed a range of apps to tackle environmental problems through the crowd sourcing of biological data using smartphones. The team is based in the research and development division of IT Services at Bristol University, which explores how the internet and other technologies can aid research, future learning and management processes.

Dave Kilbey, Nature Locator project manager said: "Smartphone apps like this one have the potential to transform the way we record and monitor wildlife populations owing to a combination of useful features such as GPS location fixing, help with making a correct identification and the ability to take and submit images with records.  This makes submitted records more accurate than ever before and also enables them to be verified.  In addition apps allow you to submit records the moment you spot something, which means there's no more getting distracted by the long list of chores you have to do when you return home."

Within the App each of the species has a distribution map and habitat information to give guidance on where they are most likely to be found.  Additional information, including photos and a simple id key, is provided to assist identification.

Dr David Roy, Head of the Biological Records Centre at the Centre for Ecology & Hydrology said: “Mobile Apps offer exciting possibilities for collecting high quality wildlife sightings.  It is becoming ever easier for anyone to get involved in recording and make an important contribution to tracking changes to our natural environment. “

The development of the app was funded by the Natural Environment Research Council and the Centre for Ecology & Hydrology. Results from the project will be posted on

Wildlife recording and the UK Ladybird Survey

For hundreds of years people in Britain have been recording when and where they see plants, animals and other wildlife. For the last fifty years The Biological Records Centre within the Centre for Ecology & Hydrology has helped people to record many different species by working with over 80 national recording schemes covering plants and insects.

The UK Ladybird Survey is one such scheme. Launched in 1968, it collates and analyses records of ladybird species found across the UK, and maps their distributions. The information gathered is used by scientists to see how wildlife is changing due to factors such as climate change and the arrival of new species. Scientists could not do this work without the help of people across the UK reporting where and when they find a species.

To date people across the country have helped track the spread of the harlequin ladybird through an on-line recording system.  More than 50,000 records have been submitted and the information has shown that some native ladybirds are declining in response to the arrival of this alien species. 

Adult ladybirds may be found at any time of the year, although more tend to be seen between March and September. Weather affects ladybird activity and it is best to look for them on a sunny day.

All ladybirds are terrestrial and searching plants is the best way to find them. Good habitats for ladybirds  include trees, hedgerows and low herbaceous plants such as nettles.

The app can be downloaded by searching for "iRecord Ladybirds" on the App Store app on your iPhone.  Further details of the app can be found on the iTunes Preview page

Further information

The Nature Locator project at the University of Bristol is developing a portfolio of projects centred on the crowd sourcing of biological data using smartphones. Its other projects include:

Conker Tree Science: Leaf Watch

The award winning Leaf Watch app sought to crowd source the most up-to-date, comprehensive data yet on the distribution of the Horse Chestnut Leaf Mining Moth, Cameraria ohridella. The production of an app was a large factor in successfully engaging the public and generating records, with 5500 records being submitted in the four month recording period, providing new insights into the moth’s distribution.


In partnership with the Environment Agency, the Centre for Ecology and Hydrology and the GB Non-Native Species Secretariat, PlantTracker aims to crowd-source data on 14 problematic non-native invasive plant species within the UK. Released in August 2012 it has already generated 3000 verified records and facilitated the early intervention in many invasive plant outbreaks.


Funded by the JISC, and in partnership with UCL and the Bat Conservation Trust, the Nature Locator project is investigating the potential for using mobile technology to enable the automatic ID of bat species using their ultrasonic calls. As of May 2013 a proof of concept prototype has been created. More information is available from here.
