Haltica oleracea, L., hitlierto commonly regarded as one of the 

 noxious flea-beetles, is quite a harmless species, as already pointed 

 out in 1912 by Heikertinger in Austria. Its food-plant is Epilobium 

 (ingustifolium, on which it is very common in Sweden. Earlier records 

 of its occurrence on hazel and oak are due to a confusion with 

 //. brevicoUis, Foudr., and H. saliceti, Weise. On cruciferous plants 

 this species will not feed even in captivity, all earlier records of injury 

 to these plants being erroneous. Of more than 200 records of injuries 

 caused by flea-beetles during 1917-1918 and accompanied by samples 

 of the beetles, H. oleracea was not found in a single case. Meligethes 

 aeneus on the other hand was often mistaken for a flea-beetle and sent 

 in as such. 



At the beginning of June the eggs are found on the underside of 

 the leaves of Epilobium angustifolium ; at the end of July the larvae 

 are full grown and descend to the ground, where they pupate, the
