Machimus atricapillus - frontal, Heeswijk-Dinther, Netherlands A frontal view of this robberfly, showing a few characteristics typical of robberflies:<br />
- The eyes never touch each other<br />
- Always bearded<br />
- The proboscis sticking through the beard (in black), its main weapon to pierce prey and suck them dry<br />
- Long grabby legs to catch prey in flight<br />
<br />
Robberflies behave quite similar to dragonflies when it comes to photography. They always know you&#039;re there yet often allow a slow approach. When they do flee, just stay in place, as they very often return to the exact same spot.<br />
