Shelter-building behavior and natural history of two pyralid caterpillars feeding on Piper stipulaceum.

Abarca M, Boege K, Zaldívar-Riverón A - J. Insect Sci. (2014)

Bottom Line: Shelter-building behavior was found to be constrained by the ontogenetic stage of caterpillars and influenced by leaf size of the host plant, Piper stipulaceum Opiz (Piperales: Piperaceae) .A similar pattern of shelter-building behavior exhibited by Tosale n. sp. near cuprealis larvae that coexisted in the same host plant is also described.Larvae of the second species were significantly less abundant than those of Lepidomys and hatched one month later in the rainy season, which could indicate some competitive interactions between these two pyralid species.

f03_01: Leaf structures inhabited by Lepidomys according to their ontogenetic stage: A. Black head individuals. B. Leaf tie. C. Trenched leaf shelter. D. Nest. High quality figures are available online.

Mentions: Lepidomys larvae built two types of shelters over their lifetime: leaf ties and trenched complex shelters. Eggs were laid in masses in the space where two leaves overlapped. The small black head instars (Figure 3A) silked overlapping leaves together and inhabited resulting leaf ties. These ties turned a yellowish color (Figure 3B) as a consequence of larval activity, and were shed from the plant after several days of larval occupancy. Predators such as spiders and scorpions were observed using these leaf ties as shelters.
