A rare bee recently sighted in Nottingham is thought to be the first of its kind spotted locally.
A photo captured an European Orchard Bee, first recorded in the south-east of Britain three years ago but the first time one has been seen in Nottingham.
A zebra jumping spider was also recorded as enthusiasts took part in an annual event to document nature.
Martin Willis, from the Nottinghamshire Wildlife Trust, said: “We’re really pleased with the response to our first every entry into the City Nature Challenge.
"Records were uploaded from all over the city, with photographs of birds, plants, fungi, insects and mammals, celebrating the rich biodiversity of our city."
The four-day challenge during April aimed to help residents and professionals better understand urban biodiversity, as nature spotters used the mobile app iNaturalist to record wildlife.
More than 100 people took part in Nottingham and there were more than 2,700 observations made, including 673 different species.
Out of the 10 areas across the UK that took part, Birmingham topped the table for the number of observations and species and Bristol and Bath had the most number of observers.
Nottingham was the smallest city that took part, recording the most observations, species and observers per-square-kilometre.

The most common recordings were of blackbirds and cow parsley, regularly spotted at this time of year.
The original plans for public events and work with local schools had to be postponed because of the coronavirus lockdown, with participants instead taking part from their homes.
