For those arriving by plane at Schiphol Airport, the best way to travel to Leiden is by train. There are regular trains leaving from platform 5 or 6 at Schiphol to Leiden Central Station. The trip takes between 15 and 25 minutes and a single fare costs about € 7,-. For the departure times of the trains please check here; information on obtaining tickets is provided here. For other transport from Schiphol Airport to Leiden see here; and for taxis here. Those coming by car, Naturalis has two parking areas next to the building. Parking will be free for participants (parking coins for leaving the parking will be provided by the organisation). 


The congress will be hosted by Naturalis Biodiversity Center (Darwinweg 2, Leiden). The meeting will be held in the Auditorium hall in Naturalis Biodiversity Center. Naturalis is a 10 minutes walk from Leiden Central Station (Leiden CS, exit west hospital LUMC). The front entrance of Naturalis is closed until 10 AM so  in the early morning you have to use the back entrance.  You have free access to the exhibitions of Naturalis, showing your badge. 

The evening program (drinks, diner) both on 31st March and 1st April will be held at Restaurant Loetje, Hooigracht 23, Leiden, a 20 minutes walk from Leiden Central Station. Walking route is shown here.  


All Covid restrictions have been lifted in the Netherlands. However, the number of infections is still high and you can still get infected. We therefore recommend to stay careful during the congress. If you have medical complaints, take a self test (you will find one in your welcome bag) and if you are positive, do not come to the venue. 

The program of the congress has been fixed and published below. The congress is organized as a hybrid meeting, allowing for both physical as online presentations. The meeting will be live streamed on the youtube channel of EIS Kenniscentrum Insecten. A specific link to the live stream will be mailed to all participants in the days before the congress. As the hybrid setup poses some logistical challenges, we ask all presenters to send us their presentations beforehand. The presentations will be recorded and made available on the same youtube channel 


Sign up
Those attending the meeting in person can sign up upon arrival at the icebreaker at Loetje on March 31 or upon arrival at Naturalis, in April 1 and 2. During sign up you’ll receive a name badge and welcome bag including the booklet with the program and abstracts.


Book tables
There will be some tables in the auditorium for selling books or sharing free publications and flyers. In case you intend to make use of this option it helps if you could let the organisation know beforehand by sending a mail to


In 2020 the booklet “Grasshopper Conservation in Europe” was prepared. The pdf can be downloaded here. Participants who have not yet received a hardcopy can obtain one when signing up for the congress.
