Title :

An overview of the biology of the Afrotropical butterfly genus Crudaria Wallengren, 1875 (Lepidoptera: Lycaenidae: Aphnaeinae), including some new observations


Abstract :

An overview of the biology of the lepidopteran genus Crudaria is presented, including detailed notes on, and illustrations of, the morphology and life history of the constituent species. Aphytophagy is recorded for the first time in one of the three currently recognized species and it is inferred to probably also occur in a second. Oviposition on Asteraceae is recorded for the first time for the genus. A diversity of biological characteristics within the genus are highlighted and their potential taxonomic significance is discussed. Both C. capensis and C. wykehami are confirmed as good species and we find their morphological characters to be reasonably stable. Although small regional differences were found in the male genitalia of C. leroma, they were found to be unreliable as primary taxonomic characters.     Maximum likelihood and Bayesian consensus trees of Crudaria based on mitochondrial DNA show C. leroma as two separate clades - east and west. A further molecular study, using additional genes and more material, is needed to refine the phylogeny inferred here and before any taxonomic changes are made. In addition, formal designation of a leroma type is recommended in order to relate to one or other of the groups of C. leroma sensu lato.

AFRICAN BUTTERFLY NEWS: EARLY SUMMER EDITION NOVEMBER/ DECEMBER 2018 


Abstract :

Welcome to the Early Summer edition of African Butterfly News! Without wishing to be a prophet of doom, the early part of the 2018 – 2019 season has been fairly disastrous. With one or two exceptions, butterfly numbers have crashed and there are no records whatsoever for several rare spring Lycaenidae throughout the country. Hopefully the situation will improve, but please help me monitor the situation by sending speciescounts to the Butterfly Index – refer to the FEATURES section of this newsletter. Despite the relative paucity of butterflies, I’ve received a record number of contributions for this edition of the newsletter – thanks to all the contributors!

Title :

Observations on larval tunneling by the enigmatic South African Keurboom Moth Leto venus (Cramer, 1780) (Lepidoptera: Hepialidae).


Abstract :

Details of tunneling and feeding by larvae of Leto venus are described and illustrated for the first time. Larval tunnels were examined from a section of lower trunk of the host plant Virgilia oroboides ferruginea from the Garden Route Botanical Gardens. Tunnels were 255-324 mm in length and of irregular cross sectional shape and located in the outer cortex and phloem, sometimes intersecting bark. Emergent pupae protrude from the host, sometimes from a ‘cocoon’ of silk and debris that also forms a tubular extension beyond the bark surface. The location of tunnels and their short length relative to the size of the larva and duration of larval development suggests that larvae are not primarily wood consumers, but utilize a replenished food supply, perhaps grazing phloem resulting in a sustained release of nutrient rich sap. The tunneling and feeding mode of L. venus provides new insights into possible modes of evolutionary transition between general tissue feeding found in many root feeders and callus feeding that occurs in other stem boring Hepialidae.
