A Note on Insect Wing Veins and their Tracheae

JOHN SMART 1

1 Department of Zoology, University of Cambridge

Experiments involving interference with the tracheae of the nymphal fore-wing pad of the American cockroach (Periplaneta americana (Linn.)) are described and the results discussed. It is concluded that the pattern of the tracheae is not immutable and so cannot be regarded as fundamental in determining the pattern of the imaginal wing-venation; the pattern may, however, continue to be used, in the first instance, as a guide to the more fundamental pattern of the lacunae that precede the veins.
