Assassin Bug Interrupts a Moth Date - Observation of the Week, 9/10/24
Our Observation of the Week is this remarkable scene captured in India by @santosh-vithura: an Assassin Bug (potentially Euagoras plagiatus) feeding on a mating Footman Moth (Nepita conferta)!
Santosh wrote a very nice piece this week and I’m posting it in full with only some minor copy edits and added links. The paragraph with info about the two organisms was written by me and is in italics. - Tony
I have always been fascinated by nature and its living and non-living elements. I am often in awe of the invisible connections that link living creatures to one another. My work focuses on observing and recording the fine and intricate details of the natural world around me. Currently, I've chosen to photograph arthropods, which I find complex, beautiful, and a source of daily inspiration.
By profession I am a physicist but I now dedicate a significant portion of my time to taking macro photographs of insects. I strive to interfere as little as possible with my subjects, never collecting or disturbing them in their natural habitats. I feel privileged to simply observe them in the wild.
I live near the foothills of the Agasthyamala mountains in Kerala, India, where lush greenery surrounds me for most of the year. The region receives ample rainfall and is dotted with natural springs and waterfalls. The environment is pristine, and rich in flora and fauna.
In my daily routine, I spend six to seven hours scanning the short grasses and shrubs for tiny arthropods, all while keeping an eye out for snakes and scorpions. During this particular macro photoshoot, I noticed a mating pair of Nepita conferta. Nearby, I also spotted an assassin bug, Euagoras sp., which swiftly attacked the female. Typically, the female would take flight and carry both herself and the male to safety, but this time, the assassin bug claimed its meal.
Footman moths are the only member of the genus Nepita and they occur in India and Sri Lanka, living in moist habitats where the larvae can devour moss and lichens. Assassin bugs, like all bugs (order Hemiptera), have a proboscis for piercing and sucking. After piercing their prey with it, assassin bugs inject digestive juices that kill the prey and liquefy its insides, making it suitable for ingestion.
I've been photographing insects regularly for the past year and have been able to record my findings systematically using the iNaturalist app. The database and its identification tools have been incredibly helpful in my work, and I've even identified several rarely sighted arthropods with the help of the experts on iNaturalist. I'm now considering a career in professional macro photography and am planning to publish a book based on my fieldwork.

Cool photo. Sad day for the moth's former partner though....
fantastic observation
Great observation! Thanks for drawing our attention to this, @tiwane
Lucky timing and well documented!

Really cool observation - both the capture of the "behaviour and interaction" and also the quality of the picture itself. Congratulations @santosh-vithura
@santosh-vithura what are you using - what phone and what lens - is this your primary setup or do you use something else, many of your other pictures are high quality too.
@ram_k I use iphone 14 with a 25mm / 75mm clip-on lens. The ambient lighting is by using a 100-LED panel with an opaque white plastic diffuser. Due to uncertain weather conditions and soft slippery ground, it is not practical to use a camera setup.
Super observation! Your natural area sounds wonderful, and your daily field time is impressive!
Thanks for sharing your discoveries with all of us on iNaturalist, @santosh-vithura!
A rare photograph and nature's rare phenomenon indeed. Kudos to @santosh_vithura. My best wishes.
@santosh-vithura Thank you for the information, and looking forward to more wonderful observations
Ouch!
Good Observation!...sad for the Moth, but at least (I hope, if the male was predated.) they fulfilled their life-work..If she went on to lay eggs that is!
