Briefings

A new study reveals monarch butterflies can now use cellphones to communicate with humans, replacing traditional radio tags. This shift allows for more frequent location tracking and potentially better conservation monitoring. The technology reduces the weight of the tracking device from standard radio pulses to under half a gram.

Key points

• Monarch butterflies can now use cellphones to communicate with humans, replacing traditional radio tags.
• The tracking device weight was reduced from standard radio pulses to less than half a gram (0.02 ounces).

Context

This finding represents a significant technological advancement in butterfly monitoring, allowing for more frequent and reliable location tracking compared to previous radio-based methods.

Limitations

The evidence is limited to a single study published in October 2026. The specific number of monarchs using this technology, the geographic scope of the study, and the long-term effectiveness of the cellphone method remain unknown.
