Pompilid spider wasp
Pompilid spider wasp (Pepsis ruficornis), close-up photo. This specimen was found in the Dominican Republic. It is coloured metallic dark blue and purple with yellow antenna. Spider wasps are solitary and hunt spiders. Once caught, the wasp paralyses the spider and lays her eggs inside. Some species will bury the spider in a burrow. The emerging larvae feed on the still-alive spider. Photographed by the USGS Bee Inventory and Monitoring Lab: an organisation dedicated to identifying, cataloguing and monitoring bees and other insect species.

Handprint forensics. Computer artwork of a glowing handprint, with human shadows in the background by a window. Just like fingertips, the palm of the hand makes a unique print that can be compared to those found at a crime scene. Glass windows are a good place to look for such prints. Biological materials, such as human sweat, can be located by using fluorescent dyes, visible under ultraviolet light. This can help locate the fingerprints and handprints that can help police link a suspect to the scene of a crime.
