 swellings or ' bumps ' produced on the backs of 

 cattle by the parasitic larvae of this fly are only 

 too well known to the Cornish farmer, though 

 the fly itself is very rarely observed

 the larvae of this fly sent in to the schools have 

 come from the east of the county

Anthomyia. One or two anthomyid larvae, whose 

 specific identification is somewhat uncertain, do 

 considerable damage to various members of 

 the cabbage family and occasionally to turnips 

 throughout the county by eating into the stems 

 and roots, particularly in the earlier stages of 

 growth

 Chortophila albescens, Ztt. W. Cornwall (D.) 

 Phorbia cepetorum, Meade. The larvae of this fly, 



or a closely allied species, destroy large numbers 

 of spring-sown onions every year by eating 

 into the bulb when it is still small. This species 

 has been recorded by Colonel Yerbury from 

 St. Martin's, Stilly 



Pegomyia betae, Curt. The beet fly. This fly 

 had not been observed in Cornwall till 1902, 

 when crops of mangels at Netvfuay and St. 

 Agnes received a severe check in June from 

 the wholesale destruction of the foliage by ths 

 larvae. It was again noticed at Newquay in 

 1903, and some mangels were slightly affected 

 near Truro in 1905
