Chirosia crassiseta Stein, 1908
[Diptera: Anthomyiidae]


Chirosia crassiseta Stein, 1908. Wien. ent. Ztg. 27: 10.


Leaf- and stem-mine: Mine in the lowest part of the petiole, not in the pinnulae-bearing part of the rachis. Often several larvae together. Mined leaves are stunted, often incompletely rolled out. Puparium in the mine or in the ground (Bladmineerders van Europa). See de Meijere (1911a) and Brown and McGavin (1982) for details of the biology.

Larva: Larva with undivided posterior processes of the cephalopharyngeal skeleton (Bladmineerders van Europa).

Puparium: Details unknown.

Comments: Included in Redfern et al. (2002: 397, fig 645) in keys to galls. Ackland in Chandler (1978) did not indicate whether his host record was British or Foreign and is therefore included under 'Hosts in Britain' and 'Hosts elsewhere'.

Hosts in Britain:

Dennstaedtiaceae      

? Pteridium

    Ackland in Chandler, 1978: 227

Hosts elsewhere:

Dennstaedtiaceae      

? Pteridium

    Ackland in Chandler, 1978: 227
Pteridium aquilinum Bracken Hennig, 1966-73
Pteridium aquilinum Bracken Hering, 1957
Pteridium aquilinum Bracken Bladmineerders van Europa

Time of year - mines: June-July (Bladmineerders van Europa).

Time of year - adults: Unknown.
