Lumitrap transforms traditional paper-based moth recording into a streamlined digital workflow that fellow trappers have tested across hundreds of nocturnal sessions. Every trap operator knows the challenge of maintaining detailed records while managing counts in real-time under lamp light.
The app addresses this by combining timed session tracking with species-specific counters that community members can adjust with simple plus-minus buttons. Environmental metadata like cloud cover, wind conditions, and temperature readings at dusk and dawn are recorded alongside lamp type and site location, creating comprehensive records that fellow lepidopterists recognize as scientifically valuable.
Built-in photography linking allows you to document individual specimens directly within each moth record, while the four-week calendar with moon phase calculations helps you plan optimal trapping nights based on lunar conditions that experienced trappers know significantly affect catch rates.
Automatic duration tracking calculates hours under lamp from start to finish, providing precise temporal data that correlates with catch patterns throughout the night.
Individual increment controls for each moth species encountered, allowing accurate tallies without losing your place when multiple species arrive simultaneously at the light source.
Record cloud cover, wind conditions, and temperature at dusk and dawn to understand how weather influences species activity across your trapping locations.
Built-in camera links photos directly to species records, creating visual documentation that aids identification and provides shareable proof for rare sightings within the community.
Field guide with 64 common species includes wingspans, similar species notes, and twelve-month flight season visualizations to confirm identifications on-site.
On-device moon phase calculations display within a four-week calendar view, helping you schedule sessions during optimal lunar conditions that experienced moth-ers prioritize.
Lumitrap was created specifically for the lepidopterist community by developers who understand the unique challenges of nocturnal insect recording. The app reflects direct input from moth trappers who needed a digital solution that matched the rigor of traditional field notebooks while adding modern conveniences like automated timing, integrated photography, and statistical analysis.
The 64-species guide focuses on common moths encountered during routine trapping in north-west Europe, providing the identification support that matters most during active sessions when quick, confident determinations keep the recording process flowing smoothly.
Regular updates continue refining the interface based on feedback from the active user community of amateur and professional lepidopterists who depend on Lumitrap for biodiversity surveys, citizen science contributions, and personal moth population monitoring.
