Dragonflies to watch for in June

This is the second instalment of the dragonflies that are likely to be observed in Hull, with four species to look for in June.
5. Broad-bodied Chaser, Libellula depressa
Flight period from Mid May to mid August, peaking in June. Both sexes have dark markings in the base or each wing and a distinctive, flattered abdomen. Mature males have a pale blue abdomen with side yellow spots. They are very territorial and patrol their territory, chasing intruders and regularly perching in favourite spots, hanging from their perch (above). Females are brown and yellow, and when in flight they can be confused with a large wasp or hornet. Immatures look similar to females. The broad-bodied chaser prefers small, shallow, sunny ponds with bare edges. This species is still increasing in range in the area and there are few Hull records, but has been found at a private garden pond, Snuff Mill Lane and this year at Pearson Park wildlife garden.
6. Common Blue damselfly, Enallagma cyathigerum
Late April to late September, peaking in June and July. Prefers larger ponds and lakes with floating vegetation, where it often perches. It is found in several parks in Hull (East Park, Pickering Park), Noddle Hill Lake and Oak Road Lake amongst others.
7. Blue-tailed damselfly, Ishnura elegans
Late April to late September, peaking in June and July. A very common and widespread species present in a range of habitats, including polluted and brackish ponds and ditches, even rapidly colonising small garden ponds. Often very abundant when present, settled in marginal vegetation, and active even in dull weather.
8. Red-eyed Damselfly, Erythromma najas
Early May to end of August, peaking in June. A species favouring large canals and lakes with floating vegetation, where it settles, often far from the shore. In the area is found in Oak Road Lake and Noddle Hill Fishing lake, but given its habits, might be under-recorded.

I've not seen any dragon flies or damsel flies in Halifax. There's not a lot of open water here but now I'm reminded of the time of year I'll be more attentive when I visit a lake or river.

Hi Lucy, Good luck! It appears some dragonflies have been slow in emerging, so the season seems to have started late. All these 4 species are now flying in Hull so I hope the same will be true in Halifax, although we have milder temperatures in Hull so you may have an even later season.
