SUMMARY<br />

Orthetrum coerulescens is known from two records on 16 August 1998 (one captured female) and on 19 August 1998<br />

(one fly<strong>in</strong>g male). A questioned observation of Orthetrum brunneum <strong>in</strong> the same neighbourhood on 19 August 1997 might<br />

<strong>in</strong>dicate it could have occurred here earlier. Orthetrum coerulescens is a vulnerable species known from few isolated places<br />

<strong>in</strong> Flan<strong>de</strong>rs. However it seems to be more mobile than assumed and able to dwell over great distances. This way some<br />

specimens were caught (two successive years?) <strong>in</strong> our trap area.<br />
