Digital Naturalism Laboratories’ (Dinalab) Mothbox is described as a low-cost, high-performance insect monitor that includes a power-efficient and light-weight design that permits customers to deploy the platform in distant places. Its inexpensive and available {hardware} lets customers assemble their very own, because the bodily designs, electronics schematics, Pi scripts, and insect-IDing AI are free to make use of and modify to swimsuit particular person wants.
The Mothbox is designed to facilitate the invention of latest species of bugs and to gauge insect populations, which have been in decline worldwide because of local weather change, air pollution and different environmental components. In keeping with a report from Our World in Knowledge, there are 1.5 million recognized insect species, and nonetheless extra which are undiscovered. These numbers enable scientists and researchers to achieve vital insights into the well being of sure environments. Combining that info with the exercise of hundreds of species of bugs, together with different information like local weather, acoustic, or soil evaluation, can present a deep evaluation of how environments will be repaired.
“As a result of they have an inclination to have brief lives and infrequently restricted ranges, bugs can present tremendous localized information,” states Andy Quitmeyer, a member of the Dinalab crew. “For comparability, take into consideration one thing like a Jaguar, which is a uncommon discover and scientifically helpful to see on a wildlife digital camera, however they’ve giant ranges and lengthy lives. The presence of a Jaguar doesn’t essentially inform us a lot in regards to the well being of the atmosphere the place it was noticed. It might merely be touring throughout disturbed farmland to flee from a destroyed habitat elsewhere. Having an insect sensor (like a Mothbox), nonetheless, that would evaluate the exercise of hundreds of various species of bugs can spotlight variations in environmental well being in areas only a couple kilometers aside.”

Developed by the Dinalab crew, together with Andy Quitmeyer, Bri Johns, and Hubert Szczygiel, the Mothbox is the perfect software to garner information on bugs in distant places, as different identifiers can price upwards of $10,000 and are too giant to be deployed by a single particular person.
The platform’s compact type issue takes benefit of a Raspberry Pi 5 (or the Pi 4 with PiJuice for energy administration), an Arducam 64MP autofocus digital camera, and a Talentcell rechargeable battery with a 12V regulator to energy the gadget. It additionally makes use of UV and visual gentle attractors, together with custom-designed Mothbeam PCBs, to lure the bugs, a three-channel relay board for managing the lights and different peripherals, and a modified Plano 1460-00 waterproof case with laser-cut acrylic arms and epoxy-sealed lens adapter.

The Mothbox operates autonomously, following a user-defined schedule. When the schedule begins, the gadget powers on and prompts its UV gentle attractors to lure nocturnal bugs. The high-resolution digital camera then captures the critters, that are then processed utilizing open supply AI scripts, together with YOLOv8, which identifies and crops insect photographs, and a custom-made model of BioCLIP (full with a consumer interface) that assists in grouping and figuring out bugs to varied taxonomic ranges. The processed information can then be saved domestically on the gadget or uploaded to the cloud for extra evaluation.
The Mothbox may also leverage a number of completely different targets or backgrounds to spotlight bugs. These embody the usual goal, which will be illuminated by lighting from contained in the gadget; a twin goal that’s bigger than the usual however will be folded in half for straightforward portability; a quad goal that’s 4 instances bigger than the usual and needs to be positioned additional away from the digital camera, and “simply level it at one thing,” which may make the most of partitions or sheets.
Many of the targets are reduce from acrylic and are designed to suit the arms of the Mothbox, making them straightforward to hold and deploy; nonetheless the bigger targets may cause anomalies because the digital camera focuses at sure time intervals. So, suppose the goal occurs to be a sheet or different malleable materials that sways throughout a lightweight breeze. In that case, the digital camera might want to refocus with a purpose to precisely determine bugs.
The fabric ought to stay as flat as potential; in any other case elements of the picture could also be occluded by wrinkles. The identical goes for lighting, which ought to illuminate the whole goal to take care of uniformity from the middle of the goal to the perimeters. The targets themselves may also must be cleaned on occasion, as bugs, particularly moths, generally tend to defecate lots, so selecting a cloth that’s simply cleaned is good; for these cases, the crew used felt and a skinny piece of steel painted white.
The Mothbox construct course of is easy, however requires energy instruments to drill holes within the enclosure for the digital camera and holes for the bolts that join the arms. Many of the materials is acrylic and must be laser reduce to particular sizes and lengths to accommodate the mainboard and many of the electronics. The Mothbox makes use of ring lights meant for microscopes as effectively, that are disassembled and stripped of their electronics earlier than being rewired to the enclosure. These are positioned on both aspect of the digital camera to take care of uniformity and scale back lens glare.
The remainder of the construct entails connecting the Raspberry Pi, digital camera, and different electronics to the reduce acrylic items and wiring them collectively contained in the plastic, weatherproof enclosure. The Dinalab crew suggests customers can wire the Mothbox up so as to add a photo voltaic panel that can assist lengthen battery life and even tips on how to set up a weatherproof charging port if wanted.
What’s extra, the crew factors out that customers can equip the gadget with completely different light-based attractors relying on their necessities. These embody the Mothbeam made by Moritz, which presents UV and visual gentle attractors, inside and exterior 12V UV lights, and extra.
As soon as the Mothbox is accomplished, it merely must be flashed with the crew’s newest Mothbox picture, which installs on the Raspberry Pi’s SD card drive. The crew notes that the set up time is longer than regular (about 10 minutes) because it “does every kind of prep” earlier than it’s launched. This course of requires a second boot sequence, because the working system can have loaded up, and the entire gadget ought to go into “Mothbox Mode,” turning on the UV attractor and flashing the Ring Lights each minute. In fact, customers can program their very own time intervals and when to energy up and energy down the platform.
In keeping with the Dinalab crew, the Mothbox has already been deployed in over 140 places throughout Panama, the US, Ecuador, Peru, and Mexico for biodiversity monitoring conservation analysis and as an academic software that engages communities and college students in varied science tasks. The Mothbox challenge additionally just lately gained the 2025 WILDLABS Award, securing a $50,000 grant to develop a mass-manufacturable model that goals to additional scale back prices (presently prices about $375) and simplify meeting.
