Colletes hederae Schmidt & Westrich, 1993 is a cryptic bee species from the C. succinctus species-group. The previous occurrence and spreading of this species were predominantly in south-western Europe. To determine if the species was spreading in Slovak territory, Hedera helix was monitored from autumn 2015. The ivy-bee was first recorded in Slovakia during autumn 2017. This species is widespread inside and around Bratislava; however, it was not recorded under this study in any sites located eastwards. In the Czech Republic, it was not recorded in the south-east part of the country in 2017–2019. In 2020, the occurrence of this species was confirmed in many localities in the south of the country and strong populations were discovered, especially in the towns Znojmo and Mikulov. The populations likely originated from neighbouring Austria, where this species was discovered in 2006 and the localities are usually less than 100 km away from Czech and Slovak localities. A further survey could map a route of the northwards spread of this species.

Colletes hederae Schmidt & Westrich, 1993 is a cryptic species from the C. succinctus species-group with minute morphological differences useful for its identification (
The reasons for which the species enlarges its distribution area are not well understood. Several indications are pointing to the impact of the unusually high temperatures at the turn of summer and autumn resulting from global climatic change (
There are exceptions from the above mentioned northwesterly direction of the species as follows: the northern direction in Austria and Hungary (
Hedera helix was observed within the blooming period (August to October) due to the expected spreading of C. hederae to Slovakia from autumn 2015. These observations were carried out in urban areas and always in places with a connection to gardens (hedge, overgrown fence, small garden building) or parks. Cemetery walls were also frequently studied localities. Altogether, we observed flower visitors on the ivy at 42 localities in Slovakia between the years 2015–2020 (Tables

In the Czech Republic, sites with flowering ivy were found and searched for the occurrence of C. hederae. All localities were situated in the south of the country, usually very close to the border with Austria and Slovakia. In 2017, we investigated localities in Kostice, Lanžhot and Břeclav and, in 2018–2019, in Nové Hrady randomly, but the species was not discovered. In 2020, the species was recorded in Kostice and Břeclav and many other localities in the Region of Moravia, as well as in two localities in the south of Bohemia. Altogether, we studied ivy flower visitors in 44 localities in the Czech Republic (16 in Bohemia and 28 in Moravia). In Tables
We observed the insects flying around and sitting on flowers of ivy during the warmest part of the day (between 11 a.m. and 4 p.m.) from the end of August until mid-October. Observations were only carried out at temperatures higher than 18°C in warm weather, with sunny or only partially cloudy skies, with no rain and only slight wind. Each locality was studied for 45 minutes or a shorter time if the bee were discovered earlier. Specimens of C. hederae were determined in the field and several individuals (usually one pair) from each locality were collected and placed into 75% alcohol for the collection and further revision. The identity of all collected specimens was checked in the laboratory by P. Bogusch, J. Lukáš, A. Přidal, M. Šlachta and J. Straka. The collected individuals from Slovakia are deposited in the collection of P. Bogusch, J. Lukáš, A. Přidal and J. Straka and individuals from the Czech Republic in the collections of P. Bogusch, A. Přidal and M. Šlachta. Maps were created using QGIS 3.6 software, localities and bees on ivy, were photographed using a mobile phone camera.
We discovered adults of C. hederae in 19 localities in the Czech Republic (two in Bohemia and 17 in Moravia) and in 24 localities in Slovakia (Fig.
Map of the Czech Republic and Slovakia. Localities with the occurrence of Colletes hederae marked by a full circle and an empty circle were used for indication of a locality without record of the species. The nearest sites in Austria, Germany and Hungary are marked by blue circles and the possible routes of spreading towards Slovakia and the Czech Republic are shown by arrows. The species occurrence in the largest towns Brno (Czech Republic) and Bratislava (Slovakia) is shown in the maps under the top map.
In the Czech Republic, the species was first discovered in 2020 in 17 localities in the south of Moravia and in two localities in the south of Bohemia. The first record was from Znojmo, where the species was observed on flowering ivy in the garden of the administration centre of Podyjí National Park. Here, a strong population was discovered and many females were collecting pollen. Similarly, large populations were recorded in two additional sites in the same town and in Mikulov around a distance of 40 km from Znojmo, where the species was recorded in all five checked sites, forming very large populations (Fig.
In Bohemia, C. hederae was recorded in two localities in the southernmost part of the country, in relatively small populations. These localities are situated in the small town, Nové Hrady and the village, Byňov. The species was not recorded in the city České Budějovice and nearby areas, although seven sites were checked there for its occurrence.
The discovery of C. hederae in the Czech Republic and Slovakia is the latest proof of the spread of this species in northern and eastern directions. Since the species was not recorded in the sites of occurrence in Slovakia in 2015 and the Czech Republic in 2017–2018, we can suppose that C. hederae is a very new representative of the fauna of both countries. Czech and Slovak populations most likely originate from Austria, where C. hederae was first recorded in Vienna in 2006 (
Although C. hederae occurs in other neighbouring countries, it is evident that Czech and Slovak populations originated from Austria. In Germany, the species was first discovered in 1991 (
The sudden occurrence of C. hederae in the Czech Republic and Slovakia is somewhat similar to the situation in Graz, Austria (
Interestingly, the species occurs in Greece, where it is numerous on Lesbos Island, as well as occurring in the mainland (
Although several authors declared that this species is observable from September to December (
Further monitoring in the Czech Republic and Slovakia is desirable to gain a better understanding of the strategy in the spreading of this autumnal bee species, especially in the context of the possible dispersal towards the north and the east. While this species reached Slovakia in 2017 and the Czech Republic in 2020, it will be interesting to see if, when and in which direction this species will move to Poland. The Moravian Gate (Moravská brána) is considered as a migrating corridor to the north, not only for insect species (
The spread of C. hederae evidently continues as confirmed by the new records from Slovakia (2017) and Czechia (2020). These and recent records from Austria and Hungary correspond with the north spread direction. It is not clear why, until recently, the ivy bee spread predominantly northwesterly. We hypothesise that spreading to the north could be supported by the several last warm seasons (namely autumns) with a higher temperature than their usual average. Monitoring of the continuation of the spread of the ivy bee is important, not only to recognise its ecological limits, but also to verify the zoogeographic importance of the Moravian Gate as a migration route.
