Sample Metadata, Accessions, and Phenotypes for Neotropical Mimetic Lepidoptera

A 66.7 KB dataset published by Yacine Ben Chehida on figshare in April 2026. It contains sample metadata, accessions, and phenotypes related to convergent color pattern evolution in mimetic butterflies and moths. The data supports a study of genetic mechanisms across lineages that diverged between approximately 1 and 120 million years ago.

Use Cases

• Analyzing associations between genetic variants and convergent color pattern switches based on the described noncoding regions near the genes ivory and optix.
• Studying the genetic architecture of mimicry based on the described ~1 Mb inversion containing the ivory gene in a moth species.
• Investigating the role of hybridization in convergent evolution based on the described evidence from Ithomiini butterfly species.
• Comparing genetic mechanisms of convergence across large evolutionary timescales based on the described lineages spanning up to ~120 Mya.

Strengths

• Data is explicitly linked to a study of convergent evolution across lineages diverging up to ~120 million years ago.
• Includes phenotypes and metadata for seven species of Ithomiini and Heliconius butterflies and a Chetone moth.
• Published under a permissive CC-BY-4.0 license for reuse.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
