With 395 inquiries (status January 2019), the white-spotted rose beetle Oxythyrea funesta is among the frequently recorded species in our forum. In Germany, it is unmistakable due to its striking black and white color and can be easily determined also by laypersons and from photos. It is regarded as an element of the ponto-mediterranean fauna, which migrated along the Rhine and Danube into our region as a relic of post-glacial steppe period. In warm areas (Upper Rhine, Rhine-Main area, Rhineland-Palatinate), the species was limited during the 20th century and only rarely encountered. During the last 20 years, probably due to climate change, a significant spread of the species has been recorded in all areas of Germany.

With the first record for Mecklenburg-West Pomerania in our forum, the species is now known from all regions of Germany. However, there are still large gaps in the distribution pattern in the North and the East between the record in MV, the discoveries near Hamburg, Bremen and Hannover and isolated records in Brandenburg. We want to close these gaps with your support.


2.   Project

Hide

In 2019 we want to pay special attention to this species in order to further document its exciting and enormously rapid spread and to close large gaps in the distribution map.

What we ask from you:

  • Recording of each individual of Oxythyrea funesta
    We want to close the gaps in the distribution maps to evaluate direction and speed of the spreading. Here you can find our submission form

  • Precise date of discovery
    We would like to know, if there are any regional differences in the activity period of the species.

  • Precise data on place of discovery
    Originally, the species was only recorded in warm habitats. Currently, is also found in cities, gardens, etc. Please provide a description of the habitat, and submit a photo of the habitat as well, which we can evaluate internally.

  • Precise data on host plant
    The adult beetles feed on pollen and nectar mainly of Asteraceae, Rosacea, Apiaceae, Brassicacea and Fabaceae. Please let us know the host plant or submit a photo of it.

What you can expect:
  • Distribution maps updated on a daily basis
  • Monthly update of the phenology
  • Regular updates on host plants and habitats
  • Contribution and data collection for a scientific publication

3.   Recording status

In this section, we show you the most recent recording statistics. Keep track of the current number of observations and observers, maps sheets and much more. You are always up to date and can observe, how your data contribute to the entire project.

During the last four weeks, 7 new Oxythyrea observers, dikn, hapevau, hike, IVO55, ivoba, Ralf und Sonnenkäfer, joined. A warm welcome on kerbtier.de!
Top observer during the last seven days: Ralf (2 records). Keep up the good work!


5.   Distribution

Here you can have a look at the current distribution map including number of records by observer. New records from 2019 are shown in "magenta", so you can see the progress and also to identify map sheets that still lack recent records.

6.   Phenology

Here you can see the activity period of Oxythyrea funesta in the standard format. With your data, the graph will become even more representative. We recommend to have a look at our statistics module, because even now, we can see a difference in the activity period between North and South Germany (separation at the latitude of Frankfurt). So please have a watchful eye in early spring and record the first beetles of the new season.

  Dear kerbtier.de users, our new project for the white-spotted rose beetle is not even running for a week and we have already got the first new MTB for the species from you. Thank you!

In this context, we would like to point out that we of course continue to be interested in old observations that have not yet been reported here. In a few weeks, the main focus will be on this year's vegetation period. Until then, there is still plenty of time to search for old photos and to submit them, as some users have already done.

When submitting the photos please make sure to report only one observation at a time, so our system extract the date automatically. Recently, the observations were already uploaded with host plant and habitat. Perfect, that's the way it should be! If you do not know the plant species its not a problem. We will try to determine it.

And another tip: If you surf on the project page in chapter "5. Distribution", click on your user pseudonym and you can immediately see which map sheets you have reported. (  But please do not click too many and too fast! Otherwise our system thinks you are a bad bot and locks you out).
12.01.2019
  Although beginning of spring is still to come, we nevertheless announce our new mapping project for 2019, where we hope for the active support of all our users at kerbtier.de: The white-spotted rose beetle Oxythyrea funesta is unmistakable in Germany due to its striking black and white color. In warm areas (Upper Rhine, Rhine-Main area, Rhineland-Palatinate), the species was limited during the 20th century and only rarely encountered. During the last 20 years, probably due to climate change, a significant spread of the species has been recorded in all areas of Germany.

In 2019 we want to pay special attention to this species in order to further document its exciting and enormously rapid spread and to close large gaps in the distribution map with your help. We ask you to document your observations of this species and report them to us in our inquiry module. Here, on the project page, you can easily keep track of the progress.
