What these results show

These results show when people recorded a species, not when or where it occurs. Missing weeks and low counts do not mean absence or scarcity, and counts are not abundance. Contributed records reflect where, when and what people chose to observe.

Identification

How to identify it

Telling it apart

From what Ohio’s records show. Only what the records support is shown.

Often confused with

  • Black-shouldered Spinyleg Dromogomphus spinosus62 identifications worldwide named one where the other was meant
  • Cobra Clubtail Gomphurus vastus18 identifications worldwide named one where the other was meant
  • Eastern Pondhawk Erythemis simplicicollis10 identifications worldwide named one where the other was meant

From iNaturalist’s similar-species counts, refreshed monthly: confusions in Ohio first, then worldwide. Only species with an Ohio result are listed.
