Biological invasions driven by climate change are one of the major challenges of today’s native ecosystems. One species that undergoes such a phenomenon is Ameles spallanzania Rossi, 1792 (Insecta, Mantodea, Amelidae), a Mediterranean mantid with an extensive range expansion over the last few years. Although several studies mention this northward shift, only one occurrence has been published from Hungary until now. We present all the 27 new localities and data on this allochthonous species, concluding that it has established breeding populations in Hungary, with a growing number of observations suggesting continued expansion towards Central Europe.
Allochthonous species, citizen science, climate change, distribution, faunistics, invasive species
Climate change and biological invasions are significantly impacting European ecosystems (
The situation is not different in Hungary, a country in the middle of Central Europe strongly affected by climate change (see
The mantid fauna of Hungary traditionally consisted of one species, Mantis religiosa (Linnaeus, 1758), which is considered native in the country and overall in Central Europe (
The genus Ameles Burmeister, 1838 belongs to the tribe Amelini Westwood, 1889. While Amelini is widespread in the Western Palearctic, Ameles has a mainly Mediterranean distribution, ranging from the Canary Islands and Portugal in the West to Afghanistan in the East, and contains 23 species (Villani 2020). The genus is characterised by a relatively small body size of 20 mm to 40 mm, with the males being (mostly) holopterous and the females being brachypterous. They are considered xerothermophile and thermophile species and live mostly in Mediterranean maquis and garrigue (
In 2020, a single male specimen of A. spallanzania was reported from Hungary by
A. spallanzania is native in almost all of the Mediterranean countries from Morocco to Greece (
During the course of the past few years, we collected data of A. spallanzania occurrences in Hungary. To gather distributional information, we used multiple sources. We collected relevant posts from large social media groups specialised in arthropod and other animal identification, such as the group “Állathatározó” (= animal identification) on Facebook, which is the most popular social media platform in Hungary. We asked for the exact locality and other collecting information, and in two cases we managed to collect the physical specimen as well.
Apart from that, we checked popular citizen science websites like izeltlabuak.hu (a Hungarian citizen science page with almost 500000 records (end of 2024) for identification and data collection of arthropods), iNaturalist.org and the GBIF database. The GBIF database contains several occurrences of arthropods worldwide including all publicly available records from izeltlabuak.hu with a reliable identification by a relevant professional (
Identification of the individuals was based on the publications of

All of the collected individuals were preserved and placed in the

The examined individuals were identified as A. spallanzania by external characteristics shown in Fig.

In total 34 observations were recorded from all across the county except eastern parts (Appendix
Observations of A. spallanzania in Hungary (a) from 2024 (star), 2023 (rectangle), 2022 (triangle), 2021 (filled circle), 2020 and before (empty circle). Observation sites in Budapest and its close surroundings are enlarged (b). The former European distribution of A. spallanzania is shown as a dotted area (based on
Adults and nymphs were found simultaneously in a garden at Tata, NW Hungary in consecutive years after its local establishment. On the 11th of November 2024, three oothecae were found during the removal of four small roses (Rosa sp.) (Benjámin Attila Antal, Budapest, pers. comm. 2024). The oothecae were laid on the plant stems. Together with those, two oothecae of M. religiosa were found. This information indicates that A. spallanzania can reproduce in certain urban conditions in Hungary. An ootheca laid by a captured specimen found in Hungary is shown on Fig.

A. spallanzania is an allochthonous (non-native) species in Hungary, meaning that it originates from a different ecosystem, occurring outside of its natural range (
According to
Due to habitat alteration caused by climate change, an “extra area” becomes available for the expanding species to occupy, mostly northwards (
An unexpected source of dispersal of mantid species is due to their popularity with insect breeders (
As stated above, urban conditions seemingly provide a more suitable habitat for A. spallanzania in Hungary. This pattern is often observed in the early stages of biological invasions, called ‘urban heat island’ effect, where the milder urban microclimate creates a more favourable environment for species adapted to warmer climates (Yow 2007;
A. spallanzania is not the only mantid in Hungary currently expanding its range. It is worth to mention the case of the non-native H. tenuidentata, which was first introduced to Europe west of Crimea in Greece (
Besides the two introduced species, the native M. religiosa is also spreading towards north, which is clearly related to climate change, in particular the “increase in average annual temperature and milder winters” (
The question remains whether A. spallanzania will become invasive out of an established allochthonous species, and what impacts it might have on native fauna.
A. spallanzania lacked a Hungarian common name up to this study. A common name may be helpful in the practice of citizen science for species monitoring, as well as in raising public awareness. Proposed Hungarian name – “Spallanzani-törpemanó”.

Hungarian observations of Ameles spallanzania until the end of 2024. For each new record, the following information is given: locality (settlement name and geographical coordinates with four digits (if at least the name of the road is known) or two digits (if only the town is known)), observation date, information about the individuals (number, sex and life stage (O = ootheca, N = nymph, none = adult)), name of the collector or photographer. Individuals that were preserved and placed in the collection of the Hungarian Natural History Museum are marked (*). Published data of
