152 BR. J. ENT. NAT. HIST., 7: 1994 



Natural History Museum — Two display boards describing the scope and origins 

 of the Rothschild-Cockayne-Kettlewell Collection and the National Collection of 

 Lepidoptera. The Cockayne Trust and the Cockayne Research Fellowship were 

 explained. Several drawers of the National Collection were exhibited. 



Owen, D. — Part of a random sample of Callimorpha dominula L. from Cothill, 

 Oxon. in 1992, when there was a population explosion. It included no bimacula 

 Cockayne (none seen since 1959), one medionigra Cockayne (heterozygote) and two 

 approaching this, and the remainder homozygous dominula. Recent experimental work 

 has shown that the expression of medionigra is affected by temperature, many more 

 medionigra being produced in high, constant temperatures, making Ford's predictions 

 invalid. Also shown was a photograph of a C. dominula larva feeding on a spore- 

 bearing cone of Equisetum telmateia; apparently there being only one previous record 

 of the larva of a moth feeding on Equisetum in Britain.
