computer van TomThe photo site shows photos from all over the Netherlands, focusing on insects, plants, birds and landscapes in Natura 2000 areas. It is the result of an increasing interest in catching my environment in images. I am using macro- and teletechniques and I am practising in landscapes.

Tabellen (vlieg van Tom) Keys and guides to a couple of fly families (eg. Therevidae, Conopidae, Rhagionidae), sea-shells, grasshoppers and dragonflies. Both allow to name species. The keys offer a system of alternative descriptions, which lead to the name of the specimen. The guides offer short descriptions with diagnostic characters and photos.

JavaFaunist Distribution data of Robberflies and Bombylid flies in the Netherlands. Two species can be compared with respect to their distribution and activity periods. Interactive java-applet.

 

Mobiele website (tekening Tom)Mobile website which enables access to the field guides and determination keys for PDA's and smart phones. The site is optimized for the portrait screens of these devices. Now you may access the keys in the field.

 

 

Mark van Veen, Zeist, The Netherlands. I headed out already as a youngster, looking for the plants and animals in their natural habitats. I wondered what their names were and learned them step by step. This resulted in a number of insect identification keys that I published, such as a hoverfly key. I also love to photograph them, first with slides, now with the digital camera. This site reflects these interests. You will find a gallery of my photo's and various identifcation keys accompanied by identification photo's. There is also an interactieve java-applet that shows the distribution of robberflies and beeflies in the  Netherlands. Enjoy!
